A thought experiment from LessWrong claiming a future omniscient AI might retroactively punish anyone who failed to bring it into being. Banned for years for being psychologically harmful.
Roko's basilisk is a thought experiment which states that there could be an artificial superintelligence in the future that, while otherwise benevolent, would punish anyone who knew of its potential existence but did not directly contribute to its advancement or development, in order to encourage that advancement. It originated in a 2010 post at discussion board LessWrong, a rationalist community web forum. The thought experiment's name derives from the poster of the article (Roko) and the basilisk, a mythical creature capable of destroying enemies with its stare.
