But it will not destroy art or music.

Don't worry, artists were already destroyed. Pop music destroyed music, visual artists destroyed themselves .

Tech death musicians compose pieces on the level of Bach and have to have day jobs, museums have blank canvases and bananas taped to walls.

You don’t have to replace the entirety of your economic system to prevent AI data centers from being built.

obviously not, and i support people who stop them. but even there, ai isn't exceptional. streaming services like youtube or netflix, or massive online games, also consume a ton of electricity and have polluting datacenters, datacenters used for ai aren't fundamentally different from datacenters used for something else, and yet people only build movements against them when it's ai. don't get me wrong it's good that we're educating people on the harms caused by datacenters. and it's good that many of these projects are being canceled. but datacenters are a problem exacerbated by ai, not created by it.

and you're right that a communist economy would not inherently fix this. maybe there would be less datacenters overall because people (and their governments) would prioritize the health of communities over chatbots, netflix and fortnite. but datacenters are not inherent to any economic model.

for everything else tho?

• deskilling by ai is a problem because it makes you dependent on an ai company for doing the skill you used to do. without capitalism, there wouldn't be an incentive to make you dependent on a product.
• ai taking jobs is a problem because under capitalism, you need a job to live.
• ai slop creations are a problem because they're low quality trash created not for their artistic merit, but for something else, like an ad, or pure revenue (like with content farms). without capitalism there would be no incentive to pump these out as much. people would probably still create them as art, but, whatever. shitty art exists and has always existed. same goes for code.

AI is a huge umbrella term, not a very specific technology at all.

Said "science" is a handful of cherrypicked studies that cannot reliably say such things. The US has been in a downward spiral of ignorance for a little while now. And if it is caused by anything, it's a combination of poor schooling, poor parenting, and social media.

Google Maps also makes us bad at finding our way manually. Are we therefore a moron?

Getting worse at tasks doesn't make you a moron. Are you a moron because you aren't as good at mental arithmetic as you were when you practiced it for school? No.
