Tech Bros have been trying to repeat the Net Boom almost immediately after that bubble burst - I think it didn't take more than a couple of years after that Crash for the "Web 2.0" to start being paraded around like some kind of new gold rush that everybody should jump into and, as clearly visible in the list of hype techs you wrote, they just kept doubling down on the hype and the fraud ever since.

I actually was in Tech in the 90s and during the Crash, and then came back to that industry and into startups almost 2 decades later, and my feeling is that the point when the entire sector turned into nothing more than a giant grift was either a bit after the crash or, at best, just when the boom before it was peaking - I remember very clearly that in the 90s startups mostly started with somebody having a cool idea for tech, whilst in the 00s and onwards they mostly started with somebody having a business idea which was generally about setting oneself up as an intermediary in a kind of business transaction already done for decades, using the Internet and/or Smartphones to come up with a new twist for it and some way of becoming an aggregator/middle-man between both sides of the transaction.
