The main error of the AI bubble is expressed in the The Jetsons cartoon from the early 60s.
In the future, everyone obviously would be running nuclear powered cars. It was just an engineering problem to be solved. Ford made the Ford Nucleon prototype in 1958.
The nuclear optimism completely blinded people to the ridiculous idea of an individual handling nuclear material for personal use.
The AI bubble error is this idea that everyone is going to have "AGI" in their pocket. It is just a completely absurd idea that is not going to happen.
Fable was interesting from what I tried but nothing close to AGI yet here we are. The models don't get smarter and LESS restricted from here.
To me, right away it seemed that the "Mythos moment" was extraordinarily bearish for the assumptions the AI bubble is built on.
