I don't think it's a symptom of a mental breakdown. I think it's a symptom of highly successful tech people who, over time, get more enclosed by a "yes-men" bubble and start to think their shit don't stink so much that they then actually start to lose touch with what most of us call "reality". You might call that "a mental breakdown", I call that being an asshole. Over the past 5 years or so, I've start becoming numb to all of the tech leaders who I used to hold in high regard who I now think are just the boring epitome of self-involved douchebags, e.g. Musk and Andreesen, for example. It just looks like garden-variety power intoxication to me.
