Yeah I mean, probably pretty likely it's going to bust and return to a more realistic level until we really sort out how to utilize AI effectively. I imagine it being similar to the .com bust (and look at the internet/web now).
As long as there is a shortage of their main product, it'll probably keep going up. Their main competition also still seems to have difficulties catching up for gpu compute. Not saying that that can't change, but it doesn't look like it yet.
