I don’t believe China has any intention to support anyone by military means. Best case they will keep on trading and that’s it. Iran is alone. Maybe Turkey makes a crazy move to support seeing it sees itself as next in line if Iran falls. This is the biggest present to European powers, which I think will be hoping that it will keep US busy for rest of Trump’s presidency. They have the Ukraine excuse to distance themselves and let everyone get weaker while they arm themselves up. Internal political tensions in US will also give them leeway to more actively influence American politics and these will be even worse with a long war pitched against a scandal background. Then again, Trump may be a genius, get this done in a couple of months and leave everyone grasping for a new strategy.
Depends how they use them as arguably was the case with stack overflow or other resources in the past. E.g. an LLM can be a valid and useful way to start discovering or understanding code and architecture. You can ask for a summary , distill important concepts and then read in more detail about them.
I think we fall into the trap of seeing art from a consumption point of view. “Of what use is a human vs AI piece of art to Me?” Art is residing in the productive space too, the artist is considering not his/her utility but his/her presence in the world. Maybe what you describe is the way forward for art monetisation but not for art, and we know experientially how the production of real art is not always in tandem with its appreciation.
