I hope that the tech billionaires are simply blundering towards the destruction of society, rather than intentionally trying to do so with something like Effective Accelerationism. That would certainly fit with Hanlon's Razor.

I have a simple theory that tech billionaires are at least partly influenced by the sci-fi of their youth. While some of the older tech billionaires were brought up on utopian sci-fi like Star Trek, with wonderful ideas like the post-scarcity economy, some of the younger tech billionaires were brought up on the dystopian sci-fi of the 1980s. Unfortunately what seems to be happening is that they may have mistaken dystopia as a blueprint for what to build rather as a warning of what to avoid.
