Gates is insanely intelligent, like demonstratably so. Musk and Bezos are also very highly intelligent people. Do they have terrible, awful, even downright despicable views? Absolutely. But don’t be fooled, all three of those people are incredibly smart with actual high IQs (not in the braggart, “I have a very high IQ.” sense either).
Intelligence doesn’t translate to empathy or wisdom. Some of the least book smart people I’ve met have been profoundly wise at times, and some of those same people were incredibly empathetic. Unfortunately, I think all three of those people (Musk, Bezos, and Gates) are lacking in those traits, but saying they aren’t in fact measurably intelligent is only fooling yourself.
I say this as someone who was raised by a measurably very highly intelligent person who could be, and was, a complete monster at times, and had some really twisted views on the world/other people. Lucky for me I didn’t inherit that innate Intelligence I guess!
