In 2010, someone posted an argument on a rationalist forum: a future superintelligent AI might choose to torture everyone who knew it could exist but didn't help build it. The forum's founder deleted the post, banned all discussion of it for five years, and called it a genuine 'information hazard.' It backfired spectacularly — the ban made it legendary, and some readers reported real panic. Welcome to the strangest dead-end in internet philosophy, where decision theory eats itself.
Kyle Hill's clear, calm walkthrough of the idea and why it unnerved so many people. The best on-ramp — he explains the trap, then defuses it, so you can read on without losing sleep.
The primary source of the legend: the original 2010 LessWrong post, founder Eliezer Yudkowsky's furious deletion, the five-year ban, and how the whole thing became a modern digital myth.
The essay that dragged the basilisk into the mainstream. David Auerbach untangles the reasoning, the community that produced it, and why smart people took an obviously absurd idea so seriously.
Straight from the forum where it was born. LessWrong's own explainer of why the argument fails — and why they still think the panic was overblown but the underlying decision theory is worth taking seriously.
Go one level deeper. The basilisk is built on a bizarre decision-theory puzzle about a being that can predict your choices. Understand Newcomb's Paradox and the whole thing clicks into unsettling focus.
Meet the culture that grew the basilisk: the rationalist community obsessed with AI risk, Bayesian reasoning, and thought experiments — the same movement that seeded today's AI-safety debates.
