The AI bubble is kind of like the dot-com bubble in that it's a revolutionary technology that will certainly be a huge part of the future, but it's still overhyped (i.e. people are investing without regard for logic).
I'm hoping after AI comes back down to earth there will be a new glut of cheap second hand GPUs and RAM to get snapped up.
I think my comparison is apt; being a bubble and a truly society-altering technology are not mutually exclusive, and by virtue of it being a bubble, it is overhyped.
