Not that you're wrong per-se but the dotcom bubble didn't impact my life at all back in the day. It was on the news and that was it. I think this will be the same. A bunch of investors will lose their investments, maybe some adventurous pension plans will suffer a bit, but on the whole life will go on.
The impact of AI itself will be much further reaching. We better force the companies that do survive to share the wealth otherwise we're in for a tough time. But that won't have anything to do with a bursting investment bubble.
edit: Really, though. How many people lost their jobs? Obviously, this being a techy space, anecdotes will lean towards people knowing someone personally. Tech people know other tech people.
But in a country of 300 million, how many people was it? Was unemployment significantly moved by it? No, it was not, because for the most part the websites that failed did not employ very large numbers of people, and there were other jobs available in the field.
There really isn't much that can harm rich people that won't indirectly do splash damage on other people, just because their actions control so much of the economy that people depend on for survival.
The dotcom bubble was one of the middle dominos on the way to the 2008 collapse, the fed dropped interest rates to near zero and kept them there for years, investor confidence was low, so here come mortgage backed securities.
In addition, the bubble bursting and its aftermath is what allowed the big players in tech (Amazon, Google, Cisco etc) to merge to monopoly, which hasn’t been particularly good
