What does "being against it" do, though? What specific actions would you take in opposition to deep learning tech?

I'm strict on calling it un-Marxist because carrying out an anti-AI programme would rely on either an unsustainable unending struggle against everyone trying to recreate it, or going full :a-guy: and bringing us so far back into the Stone Age that we can never reindustrialize again.

Most of the problems that people describe with deep learning tech, including what you're describing, are problems with the system that it exists within, not problems with the tech itself. The abolition of capitalism is the only sustainable and permanent solution to the problem, and would be one that allows humanity to fully realize its benefits with few adverse consequences.

As of right now, I do not think any opposition to AI will actually benefit workers in any way -- the most likely outcome would be that huge media companies end up being the only people able to effectively use the technology, which will result in most of the job eliminations we would hope to prevent happening anyways. It's a fight between media companies wanting stronger copyright (look up the Mickey Mouse curve -- we're due for another expansion of copyright) and tech companies wanting to sell ridiculously overpriced cloud services, and regular artists don't get a seat at this table under our current system.
