AI as a tool can absolutely be a good thing, just like almost any tool. A tool on its own is neither good nor bad, it's just a tool that can be used. The usage is what makes it good or bad.

Yes, most of what AI is used for now is bad, but it can absolutely be a good thing in the right use cases.

AI’s primary use case so far is to further concentrate wealth with the wealthy,

Under capitalism, everything further concentrates wealth with the wealthy because the wealthy are best able to capitalize on anything. Wealth gives you the means to better pursue further wealth.

and to replace employees.

So what you're saying is that we need to dismantle every piece of automation and go back to manufacturing everything by hand with the most basic hand tools possible? Because that will maximize the number of people needed to be employed to produce, well, anything. Anything else is using technology to replace employees.

Or is it just that now we're talking about people working office jobs they thought were automation-proof getting partially automated that's made automation a bad thing?

Literally you are better off with AI - it's produced some of the most groundbreaking work in decades. You didn't watch the video, did you? AI ended up being better than humans at tasks involving protein folding, so much so that they won a Nobel prize for its use. The breakthroughs of this AI have put us forward in medical research by an order of magnitude. Many orders of magnitude in fact.

AI is more than just LLMs and Stable Diffusors. It's being used in Science by people who aren't reactionaries and anti-tech luddites to give people better vaccines faster, to discover new proteins for antivenom, to ensure a better future for people who need medical care.
