I think the article gave a well-rounded view of Glover. He came across as both depressing and egotistical, but at the same time as incredibly intelligent and funny. I was impressed by the fact that he seems to be grappling with existential questions on a much deeper level than most entertainers - many of whom seem to think that their fame entitles them to a valid opinion without any rational analysis. Glover has a solid grasp of Elon Musk's motivations (what he's trying to do with Neuralink) and his ability to seamlessly incorporate ideas like Bostrom's Simulation Argument into a comedy about race in America is striking.

Zooming out, I think that were you to graph happiness levels vs. intelligence across the population, you'd get an inverted U shape. Hence the tortured artist trope. (Realize I'm making a leap here on mainly anecdotal evidence. There are a few small studies on this but nothing I feel so confident as to link to.)

A negative worldview is what pushes us forward - the people who can envision the difference between an ideal and what society currently looks like are the ones who affect change in the world.
