This is complete nonsense. An LLM has no ability to innovate or 'try new things'.
Just what the shit do you think Google/Microsoft/Amazon are pouring billions of dollars into machine learning/AI for? The first one that creates a self improving-self learning machine wins the game (or destroys the earth with a paperclip maximizer).
You and your human intelligence are not magic. You're biological hardware and software that a lot of people are spending a lot of time and effort on reproducing in a digital format.
This is (materialistic) nihilism. Materialism is a philosophy and not a new one, but an exceedingly sterile one, in my view. If you want to take that philosophical position you can, but others are free to reject it (and most people do) because it is only a philosophical position, not a proved description of reality (how can it be?).
Honestly as a human who grasps how the economy works, this doesn't sound like a good thing, but I don't see any path to trying the fundamental changes that would be required for really good general AI to not be an absolute Depression generator.
The only thing I'm wondering is, will the wealthiest ones, who actually have any power to influence these fundamental thing, figure this out before it's too late? I really doubt your Musks and Bezoses would enjoy living out their lives on ring-fenced compounds or remote islands while the rest of the world devolves into the Hunger Games.
