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".
The problem is we got autonomous cars backwards. We needed multimodal GPT first. GPT-4 can look at a picture can tell you what's happening very clearly. Now, chain this together really fast and you have something that could be used for driving. I'm making no bets on when the hardware/models will be fast/cheap/power efficient enough to support this.
>but it's not changing the world
Eh, no, it is changed the world in a vast number of ways, but not spread very equally. On the scientific/AI side a whole bunch of "20 years away" and "We may never accomplish" have been changed to "now". On the language side things GPT has put any translation service on notice. Summerizers too.
I've never been a crypto fan. I believe there are purposes for it, but at the same time I have a bank that does all the same things.
What I do (did?) not have is an AI that actually solve real life problems that I run into now, and that's something that is both highly useful, and something that many people are willing to pay for.
Again, that's a belief :). Could totally be that they never become a thing, and nobody would be surprised.
It took longer than the likes of Tesla said, but it certainly hasn't been taking longer than a whole lot of people expected.
My prediction is that we're much more than a few years away from it becoming a reality in the way people imagine.
