I absolutely love how cypto (blockchain) works but have yet to see a good use case that's not a pyramid scheme. :)

LLM/AI I'll never be good for everything. But it's damn good a few things now and it'll probably transform a few more things before it runs out of tricks or actually becomes AI (if we ever find a way to make a neural network that big before we boil ourselves alive).

The whole quantum computing thing will get more interesting shortly, as long as we keep finding math tricks it's good at.

I was around and active for dotcom, I think right now, the tech is a hell of lot more interesting and promising.
