What's next.next after ChatGPT and hype of NPL

Ok, I didn't know anything about NPL, ML. Now I feel overwhelmed about all the knowledge that is going around. I also feel that when there is too much hype, the odds of being useful in a certain field decreases. So what's going to be hot after the NPL stuff becomes cold? And what is going to be hot after that new thing becomes cold as well?
