Author is misguided:

"Designing energy stores the size of an AAA battery, but with the capacity to power a cruise ship, is hard, but possible."

is false.

They missed "AI analysis implemented as an infinite number of authoritarian servants documenting the physical traits, locations, behaviors and associations of all people 24/7" in the "really bad" column.

I understand and maybe even agree with the general “vibes” here, but I think we need to be careful about making the assumption that AI will just figure out every style of “hard problem.”

It’s been really great for certain problems. It may even “cure cancer.” As it stands, AI is good at specific things and not all types of things. Yet.

Hand-waves the negatives and the positives. Makes no real effort to contend with the drawbacks of AI, and leaves out the biggest one (IMO) - the potential harm created via delegation of arbitrary authority/capability to AI, whether in government, industry, or military. But we've apparently solved alignment, so maybe it's OK.

The rest is essentially just a short list of consequential problems facing the world, with "maybe AI will help us fix it" tacked on to each paragraph.

The last two problems don't even mention the role AI would play in their solution. That's a bit of a tell.

If it can make a web page responsive and keep in bounds when I zoom in the font that would be a glorious future.

The really bad

Will be used for mass surveillance and for further destruction of the democracy. Will be used to create powerful monopoly. Will make climate change worst due to huge energy consumption. This will be unfixable, because tech CEOs who will have more power do not care at best and are far right actors at worst. "The alignment" will be defined by the people who already shown themselves sociopaths.

This would be a great essay from a 3rd grader.
