A lot of the linkedIn style "we did X with AI and saved Y" stories seem exceptionally vague and maybe entirely made up.

It makes sense that some companies will be foolish enough to believe and to pull the trigger.

Everyone involved in that decision should be the ones fired. It seems entirely avoidable with some basic testing of the chatbot while still employing these people.

taylodl•2h ago
How many times has a chatbot successfully taken care of a customer support problem you had? I have had success, but the success rate is less than 5%. Maybe even way less than 5%.

Companies need to stop looking at customer support as an expense, but rather as an opportunity to build trust and strengthen your business relationship. They warn against assessing someone when everything is going well for them - the true measure of the person is what they do when things are not going well. It's the same for companies. When your customers are experiencing problems, that's the time to shine! It's not a problem, it's an opportunity.

no_wizard•2h ago
The only time a chatbot worked for me is Amazon's, of all things. It auto approved my return after I answered a few questions.

I haven't had any chatbot outside that be useful to me. I always end up getting to the end of all the prompts only to be told I need to speak to a human or the chatbot going in a circle, in which I have to reach out to a different layer of support.

ryandrake•1h ago
I was about to say the same thing. Amazon pretty much nailed it, at least for simple, straightforward "happy path" returns and refunds. I was actually kind of shocked after the "chatbot" conversation, sitting there thinking "Really, that's it and we're done?" and sure enough the money was refunded!
kjkjadksj•1h ago
Sounds like a downgrade to me considering the previous return flow was to just press the return link and answer one multiple choice question.
rocmcd•50m ago
That's still how it is, at least for me in the US. I've never had to interact with a chat bot for anything, but maybe it depends on what you're returning.
diggan•46m ago
> I always end up getting to the end of all the prompts only to be told I need to speak to a human or the chatbot going in a circle

I've had success with just repeating "Agent please" or "I wanna talk to human" if I notice the chat bot isn't a traditional conditional-if-else-bot but an LLM, and it seems like most of them have some sort of escape-hatch they can trigger, but they're prompted to really avoid it. But if you continue sending "Agent please" over and over again, eventually it seems like the typical context-rot prevents them from avoiding the escape-hatch, and they send you along to a real human.

rtkwe•38m ago
I think that's partially because Amazon returns are the most happy path support interaction I've ever seen. They basically always grant the refund/return and it's mostly about gathering the info to get it going rather than actually resolving an issue.
mmmlinux•17m ago
the last time i tried this i got pretty far then it switched to a human and i had to provide all the same information again. and then the person ghosted me.
m463•16m ago
On the other hand, amazon chat support, which they forced on at some point, treats your time as worth zero.

I think I used to just type in my problem into a text box and press send like an email.

duxup•1h ago
I've had bad luck. Most of it very frustrating where the bot obviously doesn't understand anything.

My best luck with a chat bot was ironically only because of HN.

I was to complaining about amazon's chat bot (it would send me in an infinite loop of directions) and someone who worked at Amazon on HN told me that there were multiple chat bots, and they told me the right one use (I had to click a different link on the amazon webpage than I was clicking).

That one worked ... it took some engineer on HN to make me understand how to make it work.

wat10000•1h ago
I bet chatbots are very successful when measuring how much the interaction costs, which seems to be what most companies are measuring when it comes to customer support. The problem is that it's very easy to measure cost (how many person-minutes did it take and what's your hourly cost for support agents, or how much API usage did it take for the bot?) and very hard to measure any outcome the customer actually cares about. Fix this misaligned incentive and the rest will follow naturally, but that requires treating support as a facilitator for the rest of the business rather than as a pure cost center that needs to be minimized.
StevenWaterman•1h ago
I'm currently working on adding a bot to our support chat at TalkJS. And it's great, it has probably a 90% success rate at handling complex queries. But that's because we're throwing money at it. That chat is normally staffed by senior devs, meaning it's not unusual for a single response to cost $10 of labour.

If you approach it as a cost cutting exercise, you end up with crap. If you approach it as a way to make a better experience while you sleep, it's achievable.

ori_b•6m ago
If you're not treating it as a cost cutting exercise, how much are you spending per query on the chatbot, and what is that $10 budget per query going towards?

Can you give some examples of complex queries that it's handled?

turnsout•1h ago
I had an experience recently where the chatbot gathered details about my problem, but then referred me to a knowledgebase article. I just replied "human" and it connected me with a human, but the AI must have given them a detailed summary, because they joined the chat, said "I understand the issue, let me see what I can do," and then two minutes later, said "I went ahead and fixed that for you on the backend."

One way to look at that anecdote is "the AI failed." Another way is "the AI made the human agent about 100% more efficient." I'm pretty sure CS agents don't love gathering basic info.

Illniyar•1h ago
This is mentioned a lot, but it's still true - people on HN are not representative of the majority of users for customer support.

The majority of support tickets are repetitive and answered by a simple formula the representative churns without thinking. Which is likely easily replaceable by chatbots.

darknavi•59m ago
It will be interesting to see how this evolves over time though. As the older generation of folks who generally don't even understand what having an account means on websites exit the customer pool the purpose of support tools could significantly change.
potato3732842•59m ago
>The majority of support tickets are repetitive and answered by a simple formula the representative churns without thinking. Which is likely easily replaceable by chatbots.

I think a large fraction of those repetitive requests are covering up gaps in the customer portal/whatever by doing data entry the customer could be doing.

Like "if you need your address changed call support" type stuff.

marssaxman•50m ago
The few times I've let a company sucker me into engaging with a chatbot, it was nothing but a worse interface to searching their support website. It was capable of nothing but directing me to pages which could not help me, because what I needed was not more information about the problem I already knew I had, but someone to fix the damn problem.
libraryatnight•6m ago
Sometimes there will be a loop that's tough to break out of where the "Contact us" tells you to talk to a chat bot before putting in a ticket or showing you a phone number, and the bot won't be able to help but will spit you out to the page that tells you to talk to the chat bot rather than give you info for actual support until you find the special event chain that leads it to let you talk to people, or attempt to.

adiabatichottub•2m ago
That actually sounds like a good use case. I always wondered how support departments tracked frequent issues, beyond ye olde drop-down menu of previously categorized reasons for contact. I guess it's something people use RAGs for nowadays?

>Companies need to stop looking at customer support as an expense, but rather as an opportunity to build trust and strengthen your business relationship.

As someone that's worked in basically a service industry my entire life, good luck with this. I don't disagree, I'm just old enough to understand the world that humans build, and this type of long-term approach is dead in the current "Profits over all" culture of the US.

antonymoose•32m ago
While I generally agree with you on the consumer side, I have the opposite experience in selling Business-to-Business solutions.

I’ve worked for small firms selling software to libraries (public and university systems), enterprise managed security services (think anti-Phishing operations), and now in managed medical claims for niche practices.

In all cases, our firm has had the customer-first philosophy to make them love us. Provide rapid responses and quality outcomes, regardless of perceived cost-center metrics. That has always, in my experience, resulted in an easy contract renewal or even having fans of ours jump to a new job at a new firm and buy our product at their new job.

Turns out people aren’t as fickle and price sensitive and still highly value good service, at least when they’re spending the companies money and not their own.

graemep•22m ago
Its more "short term profits over all".

Its not just the US - I think its pretty much the norm in the west now. Things like family owned businesses take a longer term view sometimes.

mionhe•7m ago
Is there a place where it isn't dead in the world? It seems to be the attitude everywhere nowadays.
crazygringo•38m ago
Maybe 75%?

I've gotten pointed to documentation I never would have found and I doubt a human would have found. I've had returns immediately processed rather than waiting 2 days for a RMA to show up in my email. I had a subscription rate lowered (my desired outcome) when I tried to cancel a service. And I've had a software bug escalated to the appropriate team within a couple of minutes. And all these interactions were probably 10x faster, at least, than they would have been with a human.

I love chatbots for customer service. Not because they save the company money, but because they seem to save me a ton of time (no more 20 minutes of hold, followed by being put on hold for 10 minutes multiple times), and they seem to follow policies more "objectively", and they escalate easily whenever they can't handle something. It just seems like more reliable and faster outcomes for "normal" support, and then you still get a real agent for more complicated situations.

joe_the_user•32m ago
I remember the pre-AI Geico chat bot that I liked. I could call it once every six months and pay my entire balance with a few words. But then the company started leaning harder on monthly payments and the "pay entire balance" option was removed and I now must either laboriously speak-out the entire dollars and cents due or talk to a person.

What is to say that a lot of the functions that a customer service person does is getting people things they need and that the company resists giving to them. Which is to say that companies mostly need customer service agents because the company's raw impulses are so shitty they need someone with the slight independence of a customer service agent just to provide the services their customers need.

It's like why I never go to company websites despite being very web-savy. These websites only serve the company's idea of what I get and if I'm calling at all, it's because I need more than that.

Naturally, the point is an AI chat can't do customer service because it can't override policy, tell people tricks and similar things.

JoshTriplett•5m ago
> I remember the pre-AI Geico chat bot that I liked. I could call it once every six months and pay my entire balance with a few words.

That still sounds like a bot fulfilling a function that should be solved by making the product better. This could have been either 1) an autopay requiring zero interaction, or 2) if you don't want to autopay, a form you can click "pay" on.

It is consistently worse than a google search with a site: set to their website. My best interactions have been with ones that were slightly less annoying than a phone-tree to get to a CS rep.
trentnix•10m ago
"Success rate" is a tricky metric.

I had to use an Amazon chatbot a few weeks ago. It introduced itself as "Deepshikha". After that facepalm, I started down the path with its various preferred responses to get a refund on an item I bought that never arrived, had no tracking information, and was almost certainly a scam by a third-party seller. I eventually, after a few tries, selected the right combination of things to get the refund processed. But the chatbot wasn't helpful, it didn't make any decisions, and it simply served as a filter for scam refund requests.

I guarantee you that some middle-management PM and some VP at Amazon counted that interaction as a success. I'm sure that's how it ended up on their quarterly graphs and charts. After all, the customer (me) got what they wanted and the right decision was made. And, !bonus!, it used "AI", reduces cost, and had low latency. Raises and promotions are almost certainly incoming!

But the experience was abysmal and insulting, contibuting to the ongoing ensh*ttification of the Amazon experience.

I had a chatbot attempt to answer an issue I had with setting up a Shopify site yesterday. All of the information was correct, but I had already done it. A customer support rep was able to retrigger the TLS query. The chatbot knew that needed to be done, but couldn't actually do it. It suggested ways of doing it which didn't exist in the UI, which was even more frustrating
davidhariri•5m ago
Success rate depends on many factors (risk of failure, your value to the business, complexity of the ask), but it's definitely on average much higher than 5% (I sell this technology and look at the results many times a day).

> Companies need to stop looking at customer support as an expense, but rather as an opportunity to build trust and strengthen your business relationship.

This is bang on. But unfortunately many companies have top down mandates to drive costs down (without backstops for LTV retention) and they look at top line growth as separate from OpEx. It's weird and broken, but it's a side effect of the common organizational structure of most enterprises. There are companies that do not look at themselves divisionally as CX, Sales, Product, Marketing etc. and the ones I can think of do have very high NPS (apple comes to mind).

throwawayben•5m ago
I had a joint account with an ex who now lives abroad and I no longer have contact with.

I talked to the bank and there was no way to close the account without both of us present.

Recently they released a chat bot on their app and so I asked it to close the account and the bot did it for me! That's the best success I've had with a CS bot.

Possibly the policy changed in the mean-time or the lack of activity in the account for several years allowed it to happen (though the humans never told me after x years of inactivity I'd be able to close it)

sc68cal•1h ago
> Now, CBA has apologized to the fired workers. A spokesperson told Bloomberg that they can choose to come back to their prior roles, seek another position, or leave the firm with an exit payment.

So no real consequences to the Bank for these underhanded tactics, since this just returns everything back to status quo before the layoffs, perhaps with reduced overall headcount as some workers choose not to return and take the exit payment instead, but surely the numbers still worked well enough that they will do it again but be more crafty about it so they don't lose the appeal.

toomuchtodo•1h ago
True, but the union protected its workers from those at the bank. That is the value in the union. In jurisdictions without a union or parity labor policy, these workers would have no recourse for this fraud and the lies.
sc68cal•55m ago
Absolutely! The union did great. My comment is more about, what is stopping the Bank from doing this again? Because there doesn't really seem to be a downside to attempting it. When they lose, they just have to give everyone their job back, but probably end up ahead due to attrition

ranger207•1h ago
""a reduction in call volumes" by 2,000 a week" means people aren't calling in as much. How many problems people have per day is roughly constant, so the only change in how many calls they get is entirely dependent on how much people expect calling in is going to fix their problems. So a reduction in call volume means they're not fixing as many problems which means customers are less satisfied
chankstein38•46m ago
This was my read of this as well! What a stupid metric. The first thing I thought when I read that was "Yeah, that's probably because people stopped calling and started looking for another bank."

That'll be what I'll do if my bank starts replacing people with AI. Take my money out and go somewhere that isn't trash.

ec109685•23m ago
Actually call volumes increased:

“ The union took CBA to the workplace relations tribunal earlier this month as the company wasn’t being transparent about call volumes, according to a statement Thursday from the Finance Sector Union. The nation’s largest lender had said that the voice bot reduced call volumes by 2,000 a week, when union members said volumes were in fact rising and CBA had to offer staff overtime and direct team leaders to answer calls, the union said.”

As someone whose family was forced out of the rust belt to escape unions, I just feel bad for the bank. Companies need to be allowed to innovate, forcing them to rehire people when their job is replaced by new innovation is not the way forward or towards higher wages for all
surgical_fire•1h ago
Weird take, considering that according to the text of the article the "innovation" didn't bring any productivity gains.
guywithahat•1h ago
The chatbots did bring productivity gains, the union argued that it wasn't significant enough for them to lay off people. I'm not as familiar with Australian union laws, but companies shouldn't be afraid to innovate like this. Wages don't go up through government force, they go up through innovation and increased efficiency
z0r•47m ago
"Wages don't go up through government force, they go up through innovation and increased efficiency" - that might seems obvious to you but it seems to be both ahistorical and a misrepresentation of what has happened here. Unions aren't government force.

I grew up in the rust belt. I've never heard of anyone leaving to "escape unions" but rather there just being not many jobs, lots of historic pollution to deal with, and a poor future economic outlook.

Why were unions specifically to blame for your family leaving?

JumpCrisscross•53m ago
> never heard of anyone leaving to "escape unions" but rather there just being not many jobs

Union versus non-union is a quality versus quantity problem. Unions restrict the labour pool to increase wages. When that protects specialisation, it increases productivity. When it artificially constrains the labour pool, it decreases it.

A unionised job market showing unemployment (or underemployment) is usually an indication of the latter.

guywithahat•32m ago
> but rather there just being not many jobs, lots of historic pollution to deal with, and a poor future economic outlook

I have never seen someone leave due to pollution, other than just wanting to leave the city.

The poor economic outlook and lack of jobs is directly due to the unions. If there weren't unions, Detroit and Flint would still be the capital of the auto industry, and Erie PA would still be a major locamotive hub. Instead everyone was forced out because of the unions.

blackguardx•10m ago
I lived in Erie and Cleveland for a while. There are non-union shops all around and the locomotive business in Erie was owned by a declining company (GE) that divested it in a fire sale along with many other parts of their business due to too much reliance on financial engineering and not real engineering.
ranger207•55m ago
I don't think this was "forced" as in "a court told them to rehire them", as it seems the bank agreed to rehire them before the case got to the tribunal. I think this was "forced" as in "their innovations didn't work out as well as they had hoped, so they needed to hire people experienced in the job to make up for the people they had fired, and the only people that matched the description were the people they had fired"

> redundant. At that time, CBA claimed that launching the chatbot supposedly "led to a reduction in call volumes" by 2,000 a week, FSU said.

Yeah it is reduced because as soon as someone calls they're trapped in a 30 minute "I'm sorry I didn't understand, what can I help you with" And people just give up and decide, maybe the $20 ATM fee isn't worth contesting...

Then again, this means the bank may be saving money too.
