Yes and no. Under communism, we would be able to have less AI and it would be developed slower.
My statement was incomplete, AI is not just an economic venture, the big players (maily The US and China) catched on about its massive potential for informational warfare and control over their population.
As long as there's states fighting over resources and power, any technology that can be utilized to get an edge over you enemies, not just AI, can and will be pushed forward, damn the consequences. Plus if you see capitalism as an entity itself, you could also argue that it's doing this for its own survival.
Communism is not the only vision of a stateless society spanning the globe, but one whose thoughts and ideas have been well established.
You point is that AI has inherent issues, just by existing. You are correct. But I believe if we limit the application of AI to non-military uses, if we decouple it from power struggles, its benefits may outweigh its undeniable cost.
Generative AI is something inherently different. It's a bias multiplication machine. Have you ever visited CivitAI?
Yes, the application is similar. GUIs like ComfyUI are sophisticated and grant a good deal of control and creative freedom, much like Photoshop, DAWs or Blender.
All these technologies you mentioned have one thing in common they do not have in common with generative AI though: you could use them to model after the real world. Photorealism (as in: an exact representation of something existing in the non-digital realm) is achievable with all of those. It is not possible to achieve it with generative AI. AI only has its own "space" where it snatches ideas from. Gen AI can never be a gateway to art by itself, but its also way too powerful to just be a new tool.
Also I don't get how open source gen AI will lead to the proletarianization of art. What people need to create art is education, pen and paper, health, and free time. Making those accessible to everyone is much easier than to make sure everybody who wants to do "art" gets their 1000$ GPU and tons of RAM.
