Art is a reaction to life. AI is thereby incapable of producing anything with any degree of authenticity unless it conveys the experience of being an agent to the world.

What is AI if not "a reaction to life"?

With how much data goes into the frontier systems, and how much of it gets captured by them, an AI might have, in many ways, a richer grasp of human experience than the humans themselves do.

You were only ever one human. An LLM has skimmed from millions. You have seen a tree, and the AI has seen the forest it stands in.

Two comments here.

First, "AI is thereby incapable" is a hypothesis, not a fact - how would you prove that you have to "live" to produce art? You might feel this way, you may suggest some correlations here - but can you really prove that?

Second, I don't see impossibility for AI to be - to various degrees - an agent to the world. I think that's already happening actually - they are interacting with world even today, in some limited sense, through our computers and networks, and - today - not many of them actually "learn" from those interactions. But we're in the early days of this - I suspect.
