Man, I wish I had your optimism. I can see us entering "post-work", but that's only because those who own the means of production no longer require us, and our resulting crises will be much lower on Maslow's Heirarchy of Needs.
My take is that an LLM is not ever going to lead to AGI, it's fundamentally the wrong paradigm to develop true intelligence.
Either way, I doubt that will happen in my lifetime and I don't spend any time worrying about it.
