1. Andreessen is literally unwell - it reminded me of the paranoid tendencies that reared their head in 2 of my grandparents in the early/mid stages of dementia.
2. Being a billionaire can actually be so isolating, and you constantly have people blowing sunshine up your ass, that you actually start to believe that all your ideas are infallible and that anyone not in agreement with you is a worthless peon.
I mean, even if you agreed with Andreessen's point of view, presumably he wrote and posted that manifesto to persuade, as a call-to-action. Yet I don't see how anyone could read that (or write that) and not see how the blowback would be intense, and it's had the exact opposite effect of the (presumed) intent.
Of course, Andreessen could just be a collosal "rules for thee but not for me" asshole. He was crowing about free markets and "liberating" people, and about how "it's time to build", but he and his wife turned out to be the ultimate NIMBYs when it was actually their backyard: https://www.theatlantic.com/ideas/archive/2022/08/marc-andre...
