Roko's basilisk - Wikipedia

Roko's basilisk is a thought experiment which states that an otherwise benevolent artificial superintelligence (AI) in the future would be incentivized to create a virtual reality simulation to torture anyone who knew of its potential existence but did not directly contribute to its advancement or development.[1][2] It originated in a 2010 post at discussion board LessWrong, a technical forum focused on analytical rational enquiry.[1][3][4] 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. While the theory was initially dismissed as nothing but conjecture or speculation by many LessWrong users, LessWrong co-founder Eliezer Yudkowsky reported users who described symptoms such as nightmares and mental breakdowns upon reading the theory, due to its stipulation that knowing about the theory and its basilisk made you vulnerable to the basilisk itself.[1][5] This led to discussion of the basilisk on the site to be banned for five years.[1][6]
