The massive amount of capital put into AI is not going to yield results. There will be mostly losers and only a few winners. This is assuming AI sticks around and is the paradigm shift that many people believe it will be.
If it's entirely fake, just a bunch of nonsense that people wasted money on, then it will pop quickly. But if it's somewhat real, like the dot-com boom. We'll see society transformed, and a lot of failed businesses, some of them very stupid, scattered along the information superhighway.
If this is a bubble like the housing bubble. Well, remember that even though a lot of people were underwater on their mortgage. Those homes never went to zero. It was worth something to someone, but there were a lot of people who lost everything in the exchange. And a handful of people who profited a great deal.
So expect that GDP will go up, even when the AI bubble pops. And that the middle class retirement accounts are going to be absorbing most of the hit. Because someone else, probably someone very rich, is going to still come out ahead. They almost always do.
