Honestly even in the late 90s it was going down. I don't think DEC or Amiga or something else cool you can remember have anything to do with the Silicon Valley.

After the original Intel and other hardware things fame, it's a place that mostly collected parasites living off the dotcom bubble and then profanation and oligopolization of tech. The least important part - the companies making suddenly popular user applications and websites. Their main effect was negative - they reduced diversity, competition and redundancy in that.

In any case ... "AI startups".

I'm so morally prepared to dance when that bubble finally bursts. A lot of today's rattling of sabers depends on the promise of AI workers, AI drones, AI everything so that a crime would involve only a few real humans.
