You definitely got wiser—we all do—but I think there’s also a big shift in both what they think they can say safely in public and the sycophantic reinforcement they get on social media. Rich guys have always had that problem to some extent but it used to be less public—nothing like Musk just tossing out some inane insight while high and getting hundreds of thousands of fans applauding. Human brains don’t handle that well, and you can tell these guys haven’t had to defend an idea rigorously in years.

Another factor seems to be the way corporate valuations have become increasingly untethered from actual value. It’s not like there isn’t historical precedent for people getting rich by luck but thinking they’re geniuses, but the tech world has become really weird about that in ways which amplify the previous no-filter point: it’s one thing to be, say, a Netscape millionaire but parlaying that into billionaire status really gets into the point where they never have to hear unwanted criticism and are guaranteed to be treated as sources of wisdom regardless of the applicability of their experience.
