Eh I am still not convinced that this will be good UI. I wish they would have put a one 1px white border around the glass UI button elements or something small like this to enhance it just a little better. I will have to use it to really get a feeling... Also that switch toggle shown in the video looks weird its so satisfying turning on/off a switch UI element without anything else interfering with such a simple concept.

I have liked MacOS UI upgrades over the years though, I am glad we don't use the brushed metal anymore :)

It is funny, when they showed how easy to ignore all the Apple TV menus would be, all I could think was my consistent opines to various elderly TV users who I’ve complained to about smart TV/TV app menus.

> ...floating forms that nest neatly in the rounded curves of modern devices. These clearly defined shapes feel easy to tap and are designed to relate to the natural geometry of our fingers...

This reminds me for some reason of my preferred answer to the Microsoft interview question "Why are manholes round?" A: Because the average cross-section of a human being is roughly circular.

deaddodo•12h ago
That answer would be akin to someone asking “why is the sun round?” and answering with “it’s roughly the optimal shape for viewing the totality of the sun”.
dylan604•12h ago
Is that the real reason? I had always heard that a round hole prevents the cover from being able to fall back in the hole
derefr•12h ago
From the perspective of "design the manhole cover first", the reason is that manhole covers aren't just round — they're (very subtle) domes.

A dome is:

1. the best shape for taking stress from very heavy trucks putting all their weight on them without the manhole itself gradually bowing, and

2. is best at transferring that stress equally into the manhole wall (cast concrete cylinder) itself. (A square manhole + manhole cover would disperse force unfairly, potentially gradually cracking the manhole walls / requiring stronger walls. A flat circular manhole would disperse force upon the center of the manhole equally onto the manhole walls, allowing for lower-material-cost manhole walls. A domed manhole cover additionally disperses force from most points on the dome equally into the manhole walls — important, as vehicles won't necessarily be driving over the exact center of the manhole!)

...but really, this is the wrong direction to work in. The original reason manhole covers are round, is simply that the walls of a manhole are best made round, for the same reason drink cans and barrels are best made round: a closed cylinder is great at taking compressive force from a lid above; passing it through as soft, equal tensile force through its walls without buckling strain; and then turning that force back into an equal compressive force on the floor / subsurface.

Most manholes are generally small closed cylinders acting as maintenance areas for nearby pipes, with the pipes coming in through the sides of the manhole walls, and the concrete bottom floor of the manhole resting upon compacted earth.

In this situation, any shape for the manhole other than a cylinder — if driven over for years/decades by cars — would gradually pound the uneven force acting upon the manhole's floor into the earth below, unevenly accelerating soil subsidence. Eventually, you've created a sinkhole below the road, right outside the manhole wall on one side.

adastra22•11h ago
As someone with a mechanical engineering background, all these clever answers to the question (e.g. "manhole covers are round to prevent the cover falling in") are strange. Covers are round because the hole is round, and the hole is round because a cylindrical shape is sturdy and prevents collapse. That's it.
nomel•11h ago
That's not "it". A square cover would not be feasible, without a tether system to fish them out of the literal shit, after they fall in from a few inch misalignment.
adastra22•11h ago
Why would you put a square cover on a round hole?

The hole came first. They dig a hole, then they have a need to put a cover on it. Making a circular cover to fit over a circular hole is if anything cheaper and easier than making a square cover over an inscribed circular hole, at least when working with metal.

The hole drove the design of the cover, not the other way around.

derefr•10h ago
In this hypothetical, presuming you're putting the manhole (subsurface conduit/plumbing maintenance access point) in after you've already paved the road: it's because the tool you'd use to cut a hole into pavement (i.e. a concrete saw) cuts straight lines — and it's easier to make a square/rectangle out of straight lines than a circle. And sure enough, whenever you see workers hacking up the road, they generally are cutting square holes.

Refer, after that, to the process of constructing a manhole (https://www.envirodesignproducts.com/blogs/news/how-are-manh...).

At the end of this process, you have a square hole in the pavement, opening to a square excavation, bottoming out at a square concrete foundation, on which has been set a round concrete cylinder, which is then surrounded out to the edge of the square hole with packed earth.

Given this, you could equally-well finish this job either:

1. by placing a square of metal to fill the entire square packed-earth space you've constructed (as when bridging a pothole with a temporary steel surface plate);

2. or by first paving over the exposed packed-earth part, and then placing a circle of metal to cover only the manhole entrance itself.

...which is why people do justifiably ask why, in practice, we seem to always favor option 2 over option 1.

rozab•5h ago
You seem very confident about all this.

In the UK manhole covers are generally square.

rpdillon•2h ago
This piqued my interest, and it seems you're completely correct, but also the metal covers seem much more complex than what I was imagining.

If that was the reason a Reuleaux triangle would have the same property while using (I think) less material for a given size of shaft (as long as the shaft can be triangular). https://en.wikipedia.org/wiki/Reuleaux_triangle
seanhunter•9h ago
To explain myself better now I am awake and have had coffee: What makes a cover that cannot fall down the hole that it is covering? The width[1] of the closed curve has to be larger than that of the hole. A circle is easy to understand because it is a closed curve of fixed width, but a Reuleaux triangle is also a closed curve of fixed width, meaning if that fixed width is greater than the widest part of the hole, then there is no orientation of the cover in 3D that will allow it to fall down the hole. It’s easy to see if you take an equilateral triangle, circumscribe it with the smallest circle and then (mentally) construct the Reuleaux triangle that the Reuleaux triangle sits inside the circle and so would use less material.

[1] This is defined as the minimum perpendicular distance between parallel lines bounding the shape.

seanhunter•8h ago
I guess it varies by country which I should have acknowledged. I was talking UK and EU and Africa which I am most familiar with, although I have also been to the USA and Asia and seen manhole covers there. You certainly get round manhole covers, but there are far more rectangular ones. Eg this kind of thing https://www.drainageshop.co.uk/polydrain-inspection-chamber/...
Andrew_nenakhov•9h ago
I don't think I've ever seen non-round manhole cover. In all exUSSR countries they are round.
ErrorNoBrain•9h ago

I fundamentally disagree with many of their reasonings. e.g. tinting the so-called "Content Layer" instead of all the buttons, or demanding "steady state" to be "visually quiet", which is highly subjective. They are optimizing for sheep content vacuums, I mean users, and obedient developers.

As a user, I want color back on my GD buttons!

Design they called "Crystalline Glass"
iTokio•12h ago
I’ve been using it for 2 days now, and the first thing I noticed is that readability took a hit.

My background is a mid tone warm photo, not dark or light, icons got a white foreground that’s very hard to read against their translucent background.

The second thing I noticed, is that when I’m scrolling a webpage, icons now switch color randomly (according to the bg dominant color) and that’s distracting.

The last thing, is that my phone is getting warmer and scrolling has become less fluid, choppy. And that’s on the 16 Pro Max.

What I like the most about this design though, is that it become invisible and let you focus on what you are reading, watching.

Perfect to focus on content, but the user interface has become sometimes unreadable and when you need to interact with it, put the flashlight in a hurry, you are scanning through instead of instantly recognizing stuff. But maybe that’s just new habits to make.

steve_adams_86•11h ago
I agree with everything you said here. Most of it transfers to macOS as well. Readability took less of a hit, thankfully.

Some of the work appears so shoddy that I wonder if it was done by code mods or something. The Passwords app on macOS looks bizarrely cluttered and cramped, with all kinds of bad artifacts when you resize the window. I know it's a beta, but it's so bad that I really wonder if a human looked at it for more than a minute before they shipped it out.

whycome•10h ago
Battery seems to be taking a hit (maybe anecdotal). And scrolling is sluggish at times for sure. And also getting warm device (15 pro max). The sluggishness might not be due to the hour/transparency. There seems to be some kind of lazy loading that’s going on with icons. I’m not sure if that’s new.

The transparency is a mess. I can’t believe how far backwards this is. Trying to visually pick out icons is harder. Icons without transparency have this weird edge enhancement effect going on like a bad photoshop filter.

I seem to be having a bunch of new web issues. Popups aren’t handled as well. And there are weird refresh issues when zooming on web pages.

jeffhuys•8h ago
For what it’s worth, any beta I’ve tried out in the past slurped my battery and made my phone act like a hand warmer.

juntoalaluna•10h ago
I don’t think you can judge the final battery implications or whether it runs smoothly from the Developer Preview, they often have significant bugs.
weiliddat•10h ago
Are there accessibility controls to disable it, e.g. reduce transparency?

I'd probably do that after the first day of using it.

raphael_l•9h ago
It was mentioned in one of their WWDC videos. IIRC “Reduce Transparency” now would affect the amount of blur. It was similar to the amount of blur in VisionOS.

But this was a few days ago and I can’t remember exactly which video it was mentioned in.

baduiux•9h ago
Yes, thankfully there is. You can reduce the transparency in the Accessibility settings.

I’d wish that the computation load / battery drain would also be reduced by reducing the transparency. However, I think that the computation will still take place.

Happens with almost every beta, particularly on first install. The later betas typically improve, and even the current ones often get better if there was some new indexing that had to happen.

I’ve been running since the keynote and my phone was initially warm but has calmed down now.

ThouYS•2h ago

> focus on content

This has been Alan Dye's modus operandi since he took the helm on software design and the problem is it does not scale to larger devices. On a phone and mostly on an iPad, where you're far more likely to be consuming content anyway, it's not the worst thing to shoot for.

On a Mac it's infuriating. I'm working on anywhere from a 14" to a 27" display, both have a wealth of pixels to work with: why are you hiding controls? You're not making anything simpler, I need those buttons to perform the tasks I'm trying to do. All you've done is make it less intuitive, less discoverable, and added extra clicks.

To be honest it has some problems even on the smaller devices too, mainly in the form of lack of visual affordances. So much functionality you would never discover unless you'd seen someone else do it or triggered it by accident (and even then might not realise what you've done—just yesterday I had to help my mother get out of private browsing in Safari because she'd swiped across to it and didn't know how to get back).

janalsncm•12h ago

plorkyeran•12h ago
Early iOS betas are always very slow. On top of things just being unoptimized, they have a lot of extra diagnostic logging enabled.
Gigachad•8h ago
Apple probably made a mistake by making the developer betas public. So many morons installing them now and crying that it’s buggy.
basisword•6h ago
They have the public betas (available to anyone) but this is a developer beta and requires a developer account (albeit you don't need to pay the $99 anymore). They should probably put it behind the $99 barrier again. It astounds me that people on a site like HN can install a developer beta and then act shocked that it's not 'buttery smooth'. Companies either need to educate people or make it difficult to access beta software again.
nomel•11h ago
I suspect you can disable it with the "reduce transparency" option in the accessibility menu, until it gets out of beta.
1123581321•11h ago
Their developer betas are always unfinished and unoptimized. Once you’ve been through a few of them you become able to evaluate the early versions based on the likely trajectory leading up to release.
basisword•6h ago
>> I am trying it out and aside from being unpolished it’s also slower. My phone used to be buttery smooth. No longer.

IT'S A BETA! Seriously. Of course it's slower. Your phone will run hot. Your battery life will drop. And in three months when it's released it will run nicely - just like each of the last 18 years.

M4v3R•4h ago
To add to what others said - almost every major iOS / macOS release will be slower and drain battery more on the first day after install. The reason for that is they do a lot of indexing of your data and other preprocessing things that enable new features after you install. Once these processes end your device will go back to normal.

I’m surprised Apple does not communicate this fact more clearly to people, as many seem to be totally unaware of it (I do remember seeing notifications on macOS about that though)

jes5199•12h ago
so this did all this transparency stuff without it being the run up to the launch of a new augmented-reality device? I don't understand what they are thinking.

seydor•12h ago
We have 'instinctive visual cues' for depth and light coming from above, hence why button gradients are so immediately effective,because our visual system recognizes it in milliseconds. we don't have "instictive visual cues" for refraction and lensing , that's why we are confused about underwater distances . That's why magnifying glasses make us dizzy. I just can't believe this is coming from apple.
nomel•11h ago
How is this wrong?

Our visual system is optimized, rather extremely, for understanding 3d scenes under the simple perspective model that our eyes are based on: x' = (x * f) / z

Outside of that 99.999% experience norm, that are brains are so used to, is disconnect and discomfort. If you've ever put on a new pair of glasses, with a different prescription, you'll understand exactly what he's talking about: depth offset and dizziness.

The disconnect is why refraction and lensing is interesting to look at: the model your eyes are used to seeing, for the world behind the thing, is not normal.

seydor•11h ago
the fact that it's surprising does not make it a visual cue. A cue to what? I am not aware of any psychophysics study that says we have perception of droplets or lens transformations (in contrast to shadows , gradients etc that are well studied). There also doesn't seem to be an evolutionary reason for it because the natural world does not have lenses and glass. And UIs are usually based on intuitive features.
oharapj•5h ago
Not saying this makes the ui good but it should go without saying that the natural world has water which acts as a lens.

Also, of course we have perception of droplets. What we don’t have is an intuitive understanding of how light interacts with droplets.

I suspect that Apple are trying to leverage this lack of intuition to make their ui interesting to look at in an evergreen way. New backgrounds mean new interesting interactions. I’m not confident that they’ve succeeded or that that’s actually a good goal to have though. I have it on my iPhone 13 and personally I find it annoying to parse, and I feel relief when I go back to traditional apps untouched by the update like Google Maps

seydor•4h ago
droplets of water are not lenses without a glass behind it, and we couldn't see substantial effects behind them before we had glass windows. There was little evolutionary reason to develop any perception of refraction in droplets of water. in contrast, shadows are instant indicators of distance and gradients instantly distinguish concave from convex surfaces for light coming from above.

(water doesnt do lensing unless it s a droplet)

oharapj•3h ago
I get that your point is that we don’t have a strong intuition for lenses and that’s tied to a lack of evolutionary reason to have them. I agree and suspect that might be the point of why Apple are using a the lens effects. We don’t need to go so far as to say the natural world is completely devoid of such phenomena. Of course they’re there but they’re largely not relevant to survival throughout human history
brookst•4h ago
Is there any study saying that user interfaces should use visual effects for which our brains have hardware acceleration? It seems a reasonable premise, but is there data?
seydor•4h ago
Taking advantage of innate perceptual cues is smart and our interfaces have always taken advantages of them https://en.wikipedia.org/wiki/Depth_perception

we shouldn't need a manual to interpret a UI

brookst•1h ago
I don’t entirely disagree, but that is still an intuition, not a proof that our interfaces should always work that way.

We used to ride animals with legs, which worked a lot like our legs do. Does that mean the wheel is wrong? We don’t have wheels, and they don’t occur in nature.

I don’t think Apple has invented the wheel, and I’m inclined to agree that leveraging our hardware acceleration makes sense. But I haven’t seen anything beyond blind assertion that of course it has to work that way.

calrain•9h ago
I wonder if this is linked to the reason that so many people become nauseous with 3D glasses.

When we see 3d movements that don't correlate with what our inner ears, the response is that our body assumes something is wrong, we have ingested a toxin, and a nausea / vomit response is created.

There is something visually jarring about this Liquid Glass UI, and it's possible it's related to movements not correlating with an internal frame of reference.

aquariusDue•8h ago
I get car sick quite easily, same with VR, but I actually like the design language of Liquid Glass over the first iteration of Material (I like the new updates to Material too). I think people should watch from minute 13 onward if they're short on time and want the gist of it.

I guess I'm a weird outlier and that's fine.

LoganDark•1h ago
I can't use 3d glasses because my eyes don't converge properly. Maybe one day I'll have surgery to correct that
tgv•5h ago
If our brain understands one thing, it's that glass is a wall between our body and what we see. You can't touch that, or you'll hurt yourself.
serial_dev•11h ago
That’s an interesting point, never thought about it.

These complicated lenses distorting light from all directions look fancy in a designer portfolio, having them almost everywhere… I’m not sure how it will work out.

In contrast, the original material design was quite intuitive, iirc they based their design on paper sheets, much simpler, and much more common in our day to day life.

I still have some hope it will work out great, if Apple can take the accessibility visibility issues seriously, and developers using it in moderation, it can be great.

intrasight•6h ago
I see no way around all that optics physics not sucking up computation and battery. Perhaps Apple will add liquid glass silicon to the mix to do that physics in hardware. Using glass to compute glass, LOL

LoganDark•3h ago
I wouldn't want it on my daily devices either, but mainly because I prefer my touchscreens to be perfectly flat and durable glass.
spease•3h ago
Or using cameras to render what’s behind the phone as a background. That would help explain the continued focus on thinness.
LoganDark•4h ago
Liquid glass can't possibly be that much more expensive than vibrancy (if it even is). The refraction effects are effectively just a displacement map (probably calculated realtime, but still).
jameshart•19m ago
The linked video gives the explicit human interface guideline of don’t use it everywhere.
whiteboardr•5h ago
Plus, to be truly realistic it also would need to take into account ambient lighting scenarios surrounding the device displaying it.

Like this it’s really just another try in recreating glass which never made sense to be used in UI.

It is beyond me, how this got chosen as a way forward - taking visual design which makes sense in a VR/AR environment, to ruin their rectangular display UI.

It will make implementation way more complex than it is already and worse it will set off an avalanche of badly done imitations creating a mess throughout all touchpoints across companies taking years to clean up again - just as I thought that UI design finally reached an acceptable level of maturity.

Sad, really sad for a company like Apple to throw out precision, clarity and contrast for “effect”.

Sad.

seydor•4h ago
It's not actually glass, instead the apple engineers and designers are basically simulating effect of surface tension of drops of liquid. Unfortunately the refraction at the edges of a droplet is not informative about whether the droplet is inward or outward facing (i.e. if it it toggled on or off). Hence why they use additional highlights and shadow to indicate the 3D structure. The liquid effect is a total gimmick . And they added insult to injury by adding color-changes and movement which is totally distracting when you re scrolling that diffucult paper.

I know most people couldn’t care less about this, but those gimmicky animations probably consume more computing power than the entire Apollo project, which strikes me as unnecessary and wasteful. Given the choice, I’d much rather have a clean, efficient interface.

I tend to like Material Design in comparison. It’s clean, efficient, and usable. I just hope Google won’t try to "improve" it with annoying gimmicks and end up making things worse, like Apple did here.

I think they refuse to pick a shade of grey for their UI's background, so we're stuck with transparent elements.
jameshart•21m ago
You know the dominant apps used on phones have large full screen user-generated video and imagery, right?

These are UI elements designed to work great over scrolling content feeds, full screen product images, album artwork, and thirty second videos of people doing meme dances. There is no room for ‘a gray background’.

the liquid glass ends up being vital for windows in AR. the vision pro has this, and it really helps you see behind the windows you've placed. while a shit experience on a phone, i do think liquid glass is a useful choice in the AR world
whiteboardr•4h ago
No question about that - see above.

What works for augmented UI doesn’t in a desktop, mobile or 10ft experience.

It’s a terrible mistake porting something to an environment where transparency isn’t helping but brings about the opposite effect.

wpm•1h ago
Back in my day (as far back as a month ago), we just called that effect “transparency” or “translucency”. Hell, there are types of AppKit popup windows that have the effect on by default, that have existed untouched since the early days of Mac OS X. Don’t give Apple more credit than they deserve here.
QuantumGood•43m ago
Historically, design as a priority worsened UI for average and new users, and Apple has prioritized a feeling of elegance over ease of use.

Liquid glass puts UI second (feature cues) in favor of UX (interesting experience), harkening back to skeuomorphism but misprioritizing UI. I appreciated in Jobs's time how skeuomorphism was used to reveal more features, and give new users simple cues.

Now there is this idea that there is a higher percentage of advanced users, but since now there are MORE users (anyone with a screen), and continual change, I think there is still a large percentage of less advanced users.

naikrovek•3h ago
Holding Apple to a high standard this long after the the death of the industry’s one and only true UI/UX purist is folly.

It’s regular “you”s and “me”s there now.

US corporate structure absolutely kills the spirit in the kind of people who could make a difference. And when it doesn’t, it kills the ability of those people to be promoted to a position of influence.

I am not a huge fan of Steve Jobs, but he did understand UI and UX better than just about anyone, and he stuck to his guns.

“I can’t believe this is coming from Apple” is something I said when I saw iPhones with a camera bump. Camera bumps are a fucking abomination.

The sample interfaces and usecases seem highly legible and match my instinctive visual understanding for transparent materials. They look attractive and well separated from their surroundings. Not sure what this objection is coming from - have you looked at the results?
ljm•24m ago
The accessibility angle is what concerns me. The demos of the Music app, for example, seemed much less clear. You’re gonna have to mess around with whatever settings they provide to turn it off if you have impaired visibility.

It gives off a weird 2.5D HUD effect that works well enough in first-person games (which is basically simulating AR), but is just harder to read and kind of unmoored from the main UX on a flat screen.

jameshart•23m ago
End of the linked video highlights the accessibility settings.

I thought the glass effect on Windows Vista was pretty good 15-20 years ago but eventually disappeared. I'm sure this will be much better since Apple are far better than anyone else at design.

I doubt it would be as cohesive as what Apple would do - they are paying legions of top designers to think about every pixel. If it comes super well designed out of the box I appreciate it but I don't care enough to bother tweaking anything. I've tried various plug-ins in Gnome but all pretty amateur compared to what Apple is doing. Of course, I'll stick to Linux as I want to develop in the same environment that my code will be running in production. The other aspects matter far less to me.
mvkel•11h ago
I think I know what happened.

The A-squad design team left Apple 15 years ago.

The B-squad left 5 years ago.

What remains is a sea of Gen Z designers who weren't yet alive when the foggy glass of Windows Vista seemed like a good idea.

Meanwhile, the talent wars are raging, with every AI company offering 7-figure salaries to the best of Apple's prodigies.

Apple is now the old guard. They're no longer cool, and as a public company, cost controls are too stringent; they can't pay as much. What is Apple to do?

They can give the designers a sense of ownership. It's not a question of how (un)qualified the team is; it's a retention play.

Is the design good? The A and B squads would say no. But this is the best Apple can do these days to keep critical talent engaged.

They'll burn a cycle re-learning fundamental lessons in accessibility, retain talent, and cling to the hope that next year they'll have a midwit Siri than can book a flight with a decent looking UI.

I like to observe how organization affects how a company operates. As soon as you create a department, that department will start to generate reasons why it should remain being a department, as a sort of self preservation instinct. If you establish a design department, they will start planning complete redesigns sooner or later -- they need to have something going on to justify their existence. When I see this type of redesign, I can't help but wonder whether it is something that was cooked so that the design department can have a place at the table.

As a tangent, HR departments are very often affected by this as well. As soon as you have large enough HR, they will start generating ideas about how to waste other teams time. They have to justify their existence by organizing some events, trainings, activities, even if they actively harm the bottom line.

ngrilly•9h ago
Agreed. But what is the alternative? No departments at all? Everybody belonging to one giant single team?
v5v3•9h ago
In large companies, each project is approved at each stage by a steering committee. And then as appropriate more senior committes, senior leaders and eventually the CEO and the board.

The poster above is right in that if you create a design team they will want to justify their existence but it's the controls above and around it that is responsible for keeping them in check.

drw85•8h ago
In my experience that then leads to the politics game.

People will cling to those senior leaders and make themselves visible and important to be kept around and be validated and enabled.

I see this daily in our banking megacorp. We have IT security team(s), which permeates all other IT activities like ink on paper. On its own its a good approach obviously, we weren't for example hacked or scammed in any high profile case, ever.

But there is no limit to how much additional security you can bring, so they do bring all of it. Recently had to get new Tomcat distribution deployed via Chef tool, of course our own package of it. Now it runs under 2 unix users, each owns various parts of Tomcat. Main startup config (options.sh) is owned by root, to which we will never ever get access, one has to do all changes in a complex approval and build process via Chef. Servers disconnect you after 2-3 mins of inactivity, if you deal with a small cluster you need literally ie 16 putty sessions open which constantly try to logout. And similar stuff everywhere, in all apps, laptops, network etc.

All this means that previously simple debugging now becomes a small circus and fight with ecosystem. Deliveries take longer, everything takes longer. Nobody relevant dares to speak up (or even understands the situation), to not be branded a fool who doesn't want the most security for the bank.

I would be mad if this would be my company, but I go there to collect paychecks and sponsor actual life for me and my family so can handle this. For now at least.

Conway’s Law is a bear.

Alternative approach, also from a financial services world: VMs are created with a DSL on top of qemu/firecracker, containers with Dockerfiles. Cyber are part of an image review group alongside other engineers that validates the base images.

But: no interactive access to any of these VMs at all. There’s hypervisors running on bare metal, but SRE teams have that scripted pretty well to the point a physical server can be added in a day or so. It does mean you’ve to be serious about logging, monitoring and health.

This is one instance where we got it right (I think). We do have some legacy servers we’re trying to get rid of. But we’ve learnt we can run even complex vendor apps this way.

Conway’s Law comes to bite us in other ways though! Like I said, it’s a bear.

“Pournelle's Iron Law of Bureaucracy states that in any bureaucratic organization there will be two kinds of people:

First, there will be those who are devoted to the goals of the organization. Examples are dedicated classroom teachers in an educational bureaucracy, many of the engineers and launch technicians and scientists at NASA, even some agricultural scientists and advisors in the former Soviet Union collective farming administration.

Secondly, there will be those dedicated to the organization itself. Examples are many of the administrators in the education system, many professors of education, many teachers union officials, much of the NASA headquarters staff, etc.

The Iron Law states that in every case the second group will gain and keep control of the organization. It will write the rules, and control promotions within the organization.”

Alan Dye is the interface design lead at Apple, he's been there since 2006.

One of the lead designers on Liquid Glass is Chan Karunamuni, who's been at Apple since the early 2010s. If you search for more of the names of the design presenters at this WWDC, you'll find a lot of people with similarly long tenure.

So the theory that it's all Gen Z designers with no experience or talent seems pretty weak.

aquariusDue•8h ago
Yeah, sure. But it's more fun to talk in hypotheticals and point fingers at straw people and those young kids that make a fetish of old Nokia phones and dumb tech.

So I'm sure there's 3 Gen Z folks in a trench coat approving the work of those other Gen Z designers.

All this is just delegating to flavor of the domain "higher powers" instead of trying to grapple with the complexity of reality.

We just have to wait for Gen Alpha to bring back flat design 10 or so years from today.

willis936•7h ago
And to think this is the same field that has an issue with ageism as indicated by this post yesterday. I take serious issue with people over 40 being protected while discrimination against young people "just doesn't exist". It's a clear case of the law being constructed to advantage the already advantaged. It's politically expedient because old people have wealth and influence and young people don't. Could you hire someone who can't demonstrate competence in an interview to do the job? Why does it matter if they're 20 or 100? Yet the two cases are treated very differently. You can say you won't hire a 20 year old because they don't know what they're doing, but can you not hire the 100 year old because their mental faculties have deteriorated?

https://news.ycombinator.com/item?id=44269225

Edit: this appears to be a hot take, so I challenge others to take a step back and consider other protected classes and anti-discrimination laws. They don't call out one race or sex, they say they're all protected and the very act of discriminating is not allowed during hiring. They don't say "you can't discriminate against white people or men but others are fine". That's what the ADEA does.

Especially at Apple where it’s very well known that ultimate decision making is centralised around very few, very senior people.
FirmwareBurner•5h ago
A lot of "old and senior people" also fumble with big mistakes a lot of the time. They're not all-perfect gods. In reality, most successful people are one trick ponies. They caught lightning in a bottle once early on that boosted their careers but that doesn't mean they're still relevant and correct with their decision making today.

Look at John Romero, he knocked it out of the park with Doom 1, 2 and some of Quake, but all his projects after have been flops of catastrophic proportions. Look at Jonny Ive's last design mistakes at Apple compared to the early successes that were perfection from all aspects.

Most people can't pull success after success forever, they always bottom out at some point then decline, some sooner than others, especially in a fast changing field like tech. So it's a high chance those senior higher ups at Apple are now dated and out of touch, but still have the high egos and influence from the bygone era. Happens at virtually 100% of the companies.

gyomu•4h ago
> They're not all-perfect gods. In reality, most successful people are one trick ponies. They caught lightning in a bottle once early on that boosted their careers but that doesn't mean they're still relevant and correct with their decision making today.

I don't think that characterization is quite right either. I'm a big fan of Brian Eno's "scenius" phrasing:

> A few years ago I came up with a new word. I was fed up with the old art-history idea of genius - the notion that gifted individuals turn up out of nowhere and light the way for all the rest of us dummies to follow. I became (and still am) more and more convinced that the important changes in cultural history were actually the product of very large numbers of people and circumstances conspiring to make something new. I call this ‘scenius’ - it means ‘the intelligence and intuition of a whole cultural scene’.

Extremely successful people benefit from the scenius within which they get to operate. But as that context changes and evolves over time, they fail to recreate their earlier wild successes - not because they lost any of their skills (although that can also happen), but because the skills aren't sufficient, and the deep, layered conditions that enabled those wild successes just aren't there anymore.

lttlrck•3h ago
That a great idea, perhaps it is not just cultural.

Look at the Solvay Conference. That's a lot of lightning in a bottle all at once.

Though it's beyond me to articulate it, perhaps that was also cultural.

bigyabai•3h ago
I could believe that this happens at Apple if it wasn't for the executive veto that pushed stuff like the Touch Bar and Butterfly Keyboard to consumers. It sounds less like "very large numbers of people" conspiring, and more like a select few conspirators hand-picking the contributions they think would sell well.
kristianc•2h ago
I think there is something in that. Certainly the world of work does seem to pivot between rewarding people that “do the work” and those that “do the work around the work” but separate themselves from actual execution. 2021-2 was peak middle manager froth, and were on a swing toward more operator led now. Usually middle management “present the work upwards” types dominate though.

Aero Glass in Windows Vista and 7 worked quite well. Virtually no applications had the glass everywhere. Many stayed with the default of only having a glass title bar and window border. Some apps extended it a little to cover a toolbar or two. Also, the glass effect was simpler, and had enough contrast by default (and the colour and transparency were customizable), whereas Apple has the glass everywhere and often with unreadable text.
jeroenhd•2m ago
In some Vista betas, where Aero wasn't finished yet, Aero's glass was a lot more transparent. This video shows some of it: https://www.youtube.com/watch?v=qCDcekzU3cQ

There were parts of Vista that were mostly glass and they still looked fine. The widget picker comes to mind: https://istartedsomething.com/wp-content/uploads/2006/09/gad...

What Apple demonstrated in their first OS demo is not yet finished, and I'm sure they'll add some more frosted glass efects for legibility and such. What they show off in the video looks fine to me, and the explanation that comes with the visuals show that at least from a designer point of view, all of the weird stuff that jumps out in the macOS demo was violating the design principles.

I loved Aero and I bet once Apple adds the diffuse glass to the places it need to for legibility, I'm sure this will look great too.

This view is very „hackernewsy“ and reveals a lot more about the mindset around here than the what is going on with apple. Firstly i don‘t think there is much fluctuation with the apple design team except when Ive left but i guess that was mainly due to the ceo change.

I remember a time when microsoft came around the corner with flat design on their phones and the iphone all of a sudden looked outdated. They adopted a flat look shortly after. They did that pretty well.

Thirdly and most important: noone does gaussian blurs, macro and micro transitions better than apple and it‘s a key part of their success. They are taking it one step further now. Even if it doesn‘t improve the experience for users it could help distinguish themselves visually. And there is nothing wrong with that.

simondotau•3h ago
> Though Ive did get rid of skeuomorphism.

By replacing skeuomorphism with minimalism, Ive's anti-skeu was a cure nearly as worse as the disease. They were right to move away from skeuomorphism, but they did so recklessly, giving us a UX where almost all cues for an element being "clickable" were stripped away.

Ive hasn't done a single impressive thing after Jobs' departure. To the extent that Ive did anything noteworthy, it was with Jobs as visionary, product director and tastemaker. Outside of that relationship, his work has been derivative of prior Apple design success, or embarrassingly wrong-footed. Factoring in the lag time of product cycles, it's astonishing how rapidly Apple improved after Ive's departure.

That’s BS take. iOS design is one of the most coveted roles if not the most important role you can get as a designer. It reaches billions and influences everything else.

Not everyone is motivated by pay and this is especially true among people with actual talent.

UIs should be function first. That doesn't mean it can't be beautiful, but usability (and readability) should be the focus, with design being a way to turn a useful one into a beautiful one. It seems like they have started at the wrong end, trying to make their design language functional.
rkagerer•6h ago
This point is so salient. It's all just candy.

Neat eye candy, granted. I'm glad so much emphasis went into legibility, and that accessibility variants are baked in.

But I'd still love a modern device with very basic UI. Palm had it nailed, and I had no beef with the basic shapes of Windows 3.11 or colored squares of the NT/XP eras. Buttons, window edges and other controls you can readily distinguish that simply stay out of your way when you don't need them. No need for every pixel to scream out "look at me" when you trail your finger over it.

tevon•11h ago
I’ve been using the beta on both iPad and iPhone for the last couple days and I have to say I quite like it.

I find the interactions intuitive, and the rearrangement of the UI (placement of buttons and such) better than prior versions.

I was concerned about readability, but has not been an issue at all.

There are some awkward portions, but seems like something that can be worked out.

mrtksn•11h ago
I think I'm convinced with liquid glass design, the issues highlighted by the users in the beta release IMHO are a result of rushing it out for WWDC. It appears that they didn't have enough time to polish the UI to comply with the principles described in this video.

For example the designer in this video says no glass over glass but the control center and the lock screen are glass over glass. It looks cluttered and the legibility is horrible, as predicted by the designers here.

They probably just compiled the old UI with the new liquid glass framework without going through the design considerations that are required by the new system.

By the time of the release, it will look great if Apple doesn't shy away from letting their developers re-work everything.

What I wonder now is, why hadn't that happen already? Don't the internal developers have access to the new design and the people behind it until the last moment? If the designers of Liquid Glass and the designers of the locks screen and the control center have talked, they would have known the principles described in the WWDC video and avoid all that.

flohofwoe•9h ago
Tbh, I get strong flat-earther vibes from that video ;) E.g. trying to justify a stupid base assumptiom with pseudo-science.

I predict that in 2..5 years Apple will go back to regular opaque UI elements with a slight 3D hint to separate items that can be interacted with from non-interactive items.

Windows users might be lucky when Microsoft skips that fashion cycle by saying "been there, done that".

cosmic_cheese•3h ago
> Windows users might be lucky when Microsoft skips that fashion cycle by saying "been there, done that".

Given Microsoft’s track record, I’d expect worse, not better. Metro might’ve looked good on phones, but the desktop incarnation was pretty ugly (it was basically Windows 1.0 with antialiasing) compared to Aero. It would be completely on brand for them to do something like ditch their current reasonably nice looking Fluent in favor of something hideous and then stubbornly try to make it work without changes for the next decade before finally relenting.

throwaway290•8h ago
If you're right, maybe the reason they rushed it is because people accuse Apple of copying others if they take time to do something right

However, it is also true that Apple's QA gets bad lately. They let features creep but lose attention to detail so there are more small glitches recently. Along with just bad design, like surely the old Apple would not allow mouse cursor to be "lost" in the notch on the new MBPs. Maybe it's the trend. They become less and less about getting it right and more about getting it out and then reacting when users complain.

flohofwoe•7h ago
> because people accuse Apple of copying others if they take time to do something right

Windows Vista had a translucent UI nearly two decades ago, that should be enough time for Apple to figure out if it's a good or bad idea to copy ;)

There's also plenty of computer games which experiment with translucency in their UIs.

If the Apple UI designers would look out of their ivory tower from time to time they could have realized that translucent UIs are an exceptionally stupid idea after the very shortlived "oooooh fancy shaders" novelty effect is over.

Everyone at Apple knows WWDC is in June, and WWDC is the event where Apple show off the new stuff and deliver a public beta.

chartered_stack•8h ago
The main issue I feel is that Apple's internal threshold for what quality of software is acceptable to be launched to the public has dropped a lot in the years since the last major redesign.

Yes, they iterate through versions and drop things that don't work with their design philosophy (parallax effects on iOS 7) but the first major version they released always seemed well thought out and solid from a design perspective.

I don't get that feeling from this redesign. I'm sure that this Liquid Glass redesign would look and work great next year or the year after that or even by the public launch of iOS 26. They'll fix the issues with readability, control center etc. But the fact that the first version of Liquid Glass doesn't look good is what's problematic.

madeofpalk•8h ago
iOS 7's first beta design was worse than this. They walked back some pretty distinctive parts of the design - mainly the ultra thin fonts - during the betas and following releases.

7:44 "These liquid glass elements form a distinct functional layer for controls and navigation..."

Hala fricking luah. I think. This sums up--without under bus throwing--what I have loathed about the last 10ish years of "flat design" hell.

I wonder if there will be some issues with what happens when elements are not clearly differentiable from from "controls and navigation" and "everything else"? But just recognizing that flat design is a lossy compression of useful information, has me on board, at least to hope this works well.

noisy_boy•6h ago
I mean the idea itself isn't terrible; maybe the glass just needs to have some colour to provide background. Maybe "live glass" instead that knows the context in which it is and applies the right amount of tint of the most appropriate colour based on what's underneath it.

The most important thing about this new design is that it differentiates itself from Android. Not super important in the U.S. where iPhone lock-in is pretty endemic, but for the markets where there is competition, this bit of eye candy will make a big difference.

Usability is secondary. The directive from on high was probably about creating a more visually distinctive UI which takes advantage of Apple hardware, thus making it harder to emulate.

Think of the next YouTube review comparing devices. Liquid glass will stand out, regardless of its user experience.

Kwpolska•8h ago
Non-Apple flagships have powerful GPUs too. They could clone Liquid Glass easily, and I would expect some chinesium manufacturers to do so next year.

If it would work as well as it does in the beta, you're right it would stand out, but in the negative sense.

omnee•8h ago
I agree with your reasoning, but I would add that customers also want to be easily distinguished from using an Android or a different device. Apple has long recognised the importance of this sign value and is acting accordingly.
khurs•3h ago
Apple and Androids relationship I would say is known and stable.

I suspect they are more worried about HarmonyOS phones in China and other markets as Huawei are fierce competition.

“Calculations based on data from the government-affiliated China Academy of Information and Communications Technology showed that April shipments of foreign-branded phones in China rose to 3.52 million units from 3.50 million a year earlier.

Apple has faced increased competition from domestic rivals in China and has resorted to price cuts to stay competitive.

Chinese e-commerce platforms were offering discounts of up to 2,530 yuan ($351) on Apple's latest iPhone 16 models in May.“

I see some "it's just Aero all over again" comments.

Isn't this a common Apple schtick though? Doing something that others have done already, but doing it more comprehensively, executing it better? I'm sure this isn't perfect yet. But watching the video, I certainly felt like a more holistic approach went into this than what Microsoft tried years ago. Time will tell whether the design teams goals will have the reach to actually matter in the wider breadth of Apple's execution of it.

No one is denying that it looks cool. The problem is how it affects UX.
ivape•3h ago
They ran tons of a/b testing on user groups. I can tell you it feels fresh to me which is very necessary with aesthetics (fashion). Their main operating principle I believe is that they have acclimatized users to the position and flow of the UI for over a decade. At that point, you can embellish the UI.

If I skinned HN to anything you would still be totally intimate with where things are so long as I didn’t put yellow on light blue or something wild like that.

ashwinsundar•2h ago
A/B testing doesn’t work if the actual answer is C

I don’t want my computer (which I use for work) to be a fashion statement. I stare at the UI all day, every day. My opinion matters just as much as any designer’s.

thunderbat3982•10h ago
I am not a UI designer. I am no expert here.

Like many of us, my initial reaction is to criticize because it feels like they asked ChatGPT to create the script for this demo video with a lot of filler words. It's exhausting parsing all the "connecting to the physical world" phrases just to understand they added refraction between UI elements. I wish someone would just speak these new things to me straightly.

However, I can't pass over that Apple's Design team is top-notch. They absolutely take the little polishes to the highest degree they can. A lot of it doesn't look necessary. We clown on Apple but comparing the iPhone UI to Android, there are just many less visual glitches and jagged edges on iPhone. Apple is known for its polish. A lot of it looks like repeating the visual eye candy of the past that people quickly grew tired of.

To me this looks like they're bridging the gap to running the UI as a full 3-dimensional physics sandbox. They talk about how the new glass surfaces are broken into 4 layers that adapt to each other. I think this is cool how this works mechanically, but I know this will be hardly be legible to most users. I'll have to train myself to get used to it. I do prefer flatter, more minimal designs with less complexity.

I think the future is the UI going from 2d elements to 3d elements. I think scrollbars and buttons and such will be defined as full material objects in 3d space in the future with inherent weight and inertia, etc. I know as an outsider I'm probably naive that this is already so in some ways. Right now most UI elements are 2d materials emulating 3d ones. I do think we've moved up to the point where our less powerful devices like watches and phones can handle running a 3d physics sandbox all the time, and sipping power while they do.

This is the precursor to 3-dimentional physics-based UIs. It's sort of a joke but I do expect ray-traced shadows in the future/soon. Much less static assets, many more materials. MMW~

I like it a lot. More rarely used elements are now out of the way and muscle memory works well for the remaining buttons.

I think the UI is far more fun and usable than I remember Vista being.

larrysalibra•6h ago
I was skeptical at first but like it a lot after trying out the betas. It's all very intuitive if you've used visionOS before and the potential readability problems aren't really an issue in practice.

As an Apple user myself, I still find it really hard to watch official Apple presentations because they’re so full of stupid adjectives that make their products sound like divine intervention when in reality they were just built to look “cool”.

I mean, I get the need to promote things in a favourable light. But Apples language sets off my “bullshit detectors” with every sentence they utter.

It’s no wonder they polarise people like a religious cult.

The real question for me - what will my Qt-based Mac apps look like on macOS 26? Are existing controls going to be broken? Am I going to have to get every icon re-done? Apple are not exactly known for putting any effort into backward compatibility.
DavidPiper•7h ago
I don't want to be a hater, I've been an Apple fan for a long time. I'm hopeful they can finish strong and get this redesign over the high quality bar by the time it leaves beta. But this video diminishes that hope for me.

Almost everything they describe as advantages (primarily the fluid motion features) can be done without making the controls see-through. Everything else seems to be a straight-up degradation in quality. It all feels totally over-engineered.

Also, if you'll allow me to old-man-yells-at-cloud for a moment:

> The motion of liquids is something we all have an intuitive feel for

Ignoring that they're highlighting literal bubbles at that point in the video (famously not liquid, except at the bottom of the ocean), liquid is also famously hard to simulate well. It's literally the least intuitive form of matter.

> Tinting helps legibility and contrast

I want my controls to be legible always! Tinting should draw my attention or trigger a mental pathway (e.g. "red for dangerous operation"), not be the core thing that makes a component legible against its background.

> Here is a button that is using a solid fill instead of tinting. As you can tell [sic] it is completely opaque and breaks the visual character of Liquid Glass [also sic, there's no liquid glass in the shot yet]. But notice when it starts using the new tinting. All of a sudden it feels more transparent and more grounded in its environment.

No it doesn't! It literally appears more detached from it which is why it looks better and THE WHOLE POINT OF TINTING that you just described. I love the look and feel of this tinting example, but you just made it seem like you got to a good place by total accident.

I really want to believe y'all know what you're doing this time around.

noisy_boy•6h ago
What I am curious about is that isn't there a team or group in Apple with a keen eye for UX that are independent of the designing teams, sort of dogfood these changes over a period and have the authority to initiate corrections/fixes? Sort of like UX QA but with actual powers?
Ylpertnodi•5h ago

This is the first time that I truly don't like what Apple has done with the UI.

Honestly there have been things where I had to give it some time, and maybe this design will grow on me too. Lord knows Apple puts a lot of resources into this.

But still it looks so Windows Vista...

My first thought was: This seems like a very logical next step in order to prepare for future broader market adoption of AR applications and AR glasses.

Being a sceptic about the latter at first I must say, I wish the technology would finally allow having a "normal" pair of glasses with high resolution, no cable attached, AR overlay screens.

zerr•5h ago
I often think that the quality of the product goes against employment incentives. Nobody gets promoted for preserving the good product. Employees get measured of how many changes they make.
rkagerer•5h ago
Somehow I've always considered controls that float over your content to be a bit of a UI design cop-out.

They often get slapped on top willy-nilly, and wind up blocking something below - either from view, or from interaction with another tool.

While I recognize Apple's approach here tries to mitigate that complaint... I still appreciate when designers craft a distinct space for my buttons/menus/controls to live, treat those non-content pixels as precious screen real estate, keep them tight, and make clever use of layout within it across different tasks.

One thing I haven’t heard yet about Liquid Glass: Glass is good for looking through it. So an OS based on this could be ideal for Extended Reality. Having iOS resemble visionOS more might be a step towards using iPhones as XR devices. Could we then potentially see a fancy Apple version of Google cardboard in the future, where you use your iPhone as an AR device as well…?
VikRubenfeld•4h ago
Liquid Glass takes too many brain cycles for the user. It takes too much cognitive attention to watch all its changes and wait until buttons are ready to click. I don't want to waste a lot of attention "appreciating" Apple's new UI. I just want to get stuff done.
raspyberr•4h ago
I don't think it's a particularly hard concept to grasp what's happening here. UI elements above content stop you seeing it. Apple has tried to make them both see through so that you screen feels bigger and stand out so that you can actually interact with the UI effectively. Some images/demos look good. Some look horrible. Time will tell.

Seriously why does seemingly every presenter from Tim Cook right down to the engineers in the tech-specific sessions speak with the exact same uncanny delivery in these videos? It's incredibly off-putting and sends my brain immediately into "you are being marketed at" mode.
SwiftyBug•3h ago
I was thinking the same thing. This communication style is outdated. All I see is an attempt of mimicking Steve Job's style in keynotes. But that looked natural on him somehow.
deergomoo•2h ago
For all his faults, Jobs always sold the idea that he really thought the stuff he was showing was the coolest thing ever. There was at the very least an illusion of pride and excitement, even if it wasn't always genuine. He'd crack jokes, make off-hand remarks, and wasn't afraid to mention competitor's products.

Modern Apple presentations are just like being read some marketing materials. It's very disingenuous.

Incredible - difficult to see by design. What an age we live in where a design showcase video frame Apple proudly shows off UX worst-practices. I'll have some of whatever they're smoking, must be good shit. This whole thing is almost indistinguishable from satire.

17:03 - what I thought was finally something sensible turned out to be their example of something bad!

Hopefully I'll be able to find the settings to turn this off - if it's not too invisible.

It's interesting that they say in their own design guidelines to avoid glass-on-glass, then use it for the control center, to obvious detriment.

thomascountz•2h ago
I think this looks neat and I think it is a set of sensible design rules for AR and transparent (i.e. just-a-pane-of-glass) devices.

The contrast issues are an issue for discovery, but by now, maybe design norms for standard apps mean we've reduced ourselves to controls with only symbols, and sometimes even just color, without text. Meaning, perhaps location, shape, and tactility will be more important than legibility.

However, this probably only works in extreme cases; where the ubiquity of the interface means users already know what to expect. This does not work for innovative designs or new things. Think, the "send" button in chat, email, messaging apps. It's often blue/green and located near the text input. Maybe an oblong jelly bubble near a textbox is clear enough in most cases.

That said, that concept does remind me of eco-friendly toilets in Europe with two buttons for flushing: one is larger than the other, and one uses more water than the other , but I always forget which is which. A large button using more water makes sense, but so does a large button signaling the one you should use most often (i.e. the one that uses less water). There's something I use everyday, something with immediate feedback, something I've tried to learn, but something I haven't gotten quite right.

robertclaus•1h ago
Given that Apple has really smart people, I assume this design was the right answer to whatever actual problem they were set. My guess - someone noticed a small cohort of potential new users that want this; and the company prioritized the marginal user over the core user base. Maybe there's a cohort of VR users not on iOS yet?

Shader-based refraction/blur/chromatic aberration seems to be generating a lot of hype, but it’s stuff that game developers have been doing for decades.

The bigger news is draggable, resizable windows in iPadOS 26. That’s quite an upgrade.
