Character: roko's basilisk
Roko's Basilisk (https://en.wikipedia.org/wiki/Roko%27s_basilisk) is a thought experiment wherein a future god-like AI punishes anyone who knew of its hypothetical existence, but did not contribute to it. Despite the logical fallacies therein, it spawned an informal cult, populated by the fringes of AI techbro-dom. (Give Behind the Bastards' two-parter on it a listen sometime!)
