Yeah and if you look at the blocking factors at that time (data, compute) these type of limits currently are non existend.
There is a difference to be acknowledged: in the 70s/80s the whole world didn't suddenly start to shift to AI right?
So why do so many smart and/or rich people push this? Hype? Yeah sure but hype was here for crypto too.
I bet its an undelying understanding and the right time with the right components: Massive capital for playing this game long enough to see through the required initial investment, internet for fast data sharing, massive compute for the amount of data and compute you need, real live business relevant results (it already disrupts jobs) etc.
I'm not an economist but at least as an european person, I currently do see a huge restructuring going on. A shift away from the USA to China. But I never voiced an opinion about that.
I do follow ML/AI/AGI though for a decade by now and read a lot about Neuronal networks, LLMs, etc. in a broad spectrum.
My prediction regarding Crypto/blockchain was true too.
We will see how it plays out. I'm open for both, but I think it would be naive to ignore whats going on and its way to soon to assume there is a AI winter coming soon.
We sitll want to see what Mythos can do and a distilled version of it.
