I still think it was different in the early 2000s, even after the dot com bubble.
"Big Tech" had not been assembled yet. Microsoft was the only tech megacorp in town, and they were _hated_ back then. Apple was still recovering from shambles. Google was a startup nobody heard of. Facebook wasn't a thing yet.
Tech investment money wasn't on the same scale as today. Money was measured in millions instead of the billions today. Most of the money I think was still towards finance at the time. If you look at the public companies with largest market cap before 2010 ( https://en.wikipedia.org/wiki/List_of_public_corporations_by... ), you'll see there's quite a couple banks on the list.
You're absolutely correct though that this trend was foreseeable in the 1990s. Which is kinda why the dot-com boom/bust happened -- everyone knew it was the future, I guess people were just a bit too excited for the future, and the companies who'd actually create that future weren't even founded yet, leading to all the mis-investment and subsequent bust.
