The dotcom bubble burst because the development of the internet could not keep up with expectations, even though investors were correct in principle with their assumption it would generate swaths of wealth. For AI the hope is that AI itself will start to push its own development and adoption sooner rather than later, so the timing issue that killed dotcom investors might instead make AI investors insanely rich. That's why we're still seeing heaps of money getting dumped into it.

That’s a very charitable take.

Without smartphone, cellular networks etc you’d be miles off. Nobody had this in their thesis so they were plain wrong.
