The billionaires who listened are spending hundreds of billions of dollars - soon to be trillions, if not already - on trying to prove Yudkowsky right by having an AI kill everyone. They literally tout “our product might kill everyone, idk” to raise even more cash. The only saving grace is that it is dumb as fuck and will only make the world a slightly worse place.

Given they're going out of their way to cause as much damage as possible (throwing billions into the AI money pit, boiling oceans of water and generating tons of CO~2~, looting the commons through Biblical levels of plagiarism, and destroying the commons by flooding the zone with AI-generated shit), they're arguably en route to proving Yud right in the dumbest way possible.

Not by creating a genuine AGI that turns malevolent and kills everyone, but in destroying the foundations of civilization and making the world damn-nigh uninhabitable.
