I've been wondering about this. I think it's because machine learning (in the broad sense, including other technologies like DL) is fun. It's really technically interesting to implement ML algorithms to approach problems, and even more interesting to try to solve the problems those ML algorithms cause.
Contrast this with blockchains, which are pretty boring from a technical point of view.
A large part of why I write code for a living is that it's fun. Non-technical people might not understand this, but designing code (especially optimising code) is basically a puzzle video game.
So I can see why people with brains like mine might get swept into wanting to believe that the fun project to hack on is also going to be worldchanging.
I think this would be true if people were writing LLMs, I know one person who started writing his own to run locally. Not for me but I can see where that comes from.
Using LLMs as a service just does not fall into this for me though, about as far from profiling and performance optimisation (which I like and agree can be puzzle game like) as I can think of.
Yeah this is a fair point and I think beats my point.
