These people suffer from a severe lack of imagination. Raised to pursue success along a solitary economic metric, they ignore all arts and sciences extraneous to that pursuit. They treat the world outside their interests like a children’s game they’re not really into. Their wealth insulates them from friction so effectively there’s no incentive or pressure for them to develop an imagination, or diversify their knowledge to the point where an imagination might emerge on its own.

That’s the startling thing about these tech guys: they are utterly oblivious to life outside of their extremely narrow little domain, and they occupy that domain largely because they never had the imagination or curiosity to look past it. The Silicon Valley milieu they grew up in told them that success consisted in this one thing, and they just swallowed the story and dedicated their lives to it without ever pausing to think for themselves. They’re rich financially but in other ways everyone can see how impoverished they are except them.
