The internet survived the Dotcom bubble. Many businesses died, but some survived. The glut of hardware from the dead will end up in the hands of individuals, upstart companies, and the corporations that outlived their peers.

And that resulted in there being 5 websites with fewer people self-hosting so I don’t know why you use that as an example of decentralization.

If there is a general demand for AI after the AI bubble like there was for the internet post dotcom bubble then people will always gravitate toward the most convenient way to get it which is through the cloud powered by someone else super computer.
