I don't know, I don't see it this way. Bitcoin at the very beginning was an impressive piece of technology (still is), but it clearly did more harm than good.
Autonomous cars had some very impressive demos, and don't seem to have evolved much in a few years (it's impressive, but not good enough).
AI is making very impressive demos now, but it's not changing the world (what seems to work really well right now is to generate convincing disinformation at scale, which is not good).
To me it's all the same: impressive demo, but what matters is not the first 80%, it's the last 20. Everyone seems to be building infrastructure around what AI will become. Just like people built entire companies betting on the fact that cryptocurrencies would become global (they have not), or that blockchain would be useful outside from cryptocurrencies (it is not). Or like people built entire companies around "the new world with autonomous vehicles".
