It's possible that AI is the greatest technological leap forward since the Industrial Revolution, and simultaneously a bubble that will pop in the near future.

I don't know much about the economics side; TFA gives a barrage of stats that seem to make a compelling case for bubblehood. OTOH, the claims about the utility of LLMs being unmeasurable are weak (the same criticism applies to hiring programmers, or indeed most office workers) and the metal spider straw man is frankly embarrassing to anybody who has actually used recent frontier agents for programming and seen what they can do.
