In the dot com boom we got sites like Amazon, Google, etc. And AOL was providing internet service. Not a good service. AOL was insanely overvalued, (like insanely overvalued, it was ridiculous) but they were providing a service.
But we also got a hell of a lot of businesses which were just "existing business X... but on the internet!"
It's not too dissimilar to how it is with AI now really. "We're doing what we did before... but now with AI technology!"
If it follows the dot com boom-bust pattern, there will be some companies that will survive it and they will become extremely valuable the future. But most will go under. This will result in an AI oligopoly among the companies that survive.
