Give it a few years, and it'll be pared down to a couple of real use cases with some very strong limitations.
Unlike crypto, which was all hype, no substance.
The threat to NVIDIA is probably from startups also working in the space of machine learning acceleration, not from industry demand itself.
If anything, ML will just move more and more from "tech"[bro] type companies and into more and more broader industry. Aerospace & defense, manufacturing automation, etc. etc.
It's not about chatbots and AGI, it's about dealing with huge quantities of data, and that's not going away.
Someone somewhere will always need to run a bigger, better simulation and Nvidia is more than ready to provide the hardware for that.
Maybe Apple’s iPhone grift will end soon too!!
