I remember when a lot of these Silicon Valley types were centrist liberals with a libertarian edge. Many of them voted for Obama. Now they've all seemed to have moved to the hard authoritarian right.
I believe the bulk of it has to do with a "Revenge of the Nerds" mentality.
The days of the passionate tech geeks such as Steve Wozniak and people who wanted to get into tech to genuinely benefit society are largely becoming a distant memory.
Now, the tech world is filled with angry weirdos obsessed with "logic", cryptocurrency, and genetic determinism who all want to make as much money as quickly as possible to get back at the "Chads" and "Tyrones" who made fun of them growing up.
Notice how damn near every "groyper" and self-described "Christian Nationalist" speaks with a whiny, awkward, nerdy voice rife with speech impediments.
No way in hell they didn't get bullied growing up.
This shyt is personal for them.
