I always find these "anti-AI" AI believer takes fascinating. If true AGI (which you are describing) comes to pass, there will certainly be massive societal consequences, and I'm not saying there won't be any dangers. But the economics in the resulting post-scarcity regime will be so far removed from our current world that I doubt any of this economic analysis will be even close to the mark.

I think the disconnect is that you are imagining a world where somehow LLMs are able to one-shot web businesses, but robotics and real-world tech is left untouched. Once LLMs can publish in top math/physics journals with little human assistance, it's a small step to dominating NeurIPS and getting us out of our mini-winter in robotics/RL. We're going to have Skynet or Star Trek, not the current weird situation where poor people can't afford healthy food, but can afford a smartphone.
