Artificial intelligence systems we have today can be referred to as narrow AI – they perform well at specific tasks, like playing chess or Jeopardy, and some classes of problems like Atari games. Many experts predict that general AI, which would be able to perform most tasks humans can, will be developed later this century, with median estimates around 2050. When people talk about long term existential risk from the development of general AI, they commonly refer to the intelligence explosion (IE) scenario. AI risk skeptics oftenargue against AI safety concerns along the lines of “Intelligence explosion sounds like science-fiction and seems really unlikely, therefore there’s not much to worry about”. It’s unfortunate when AI safety concerns are rounded down to worries about IE. Unlike I. J. Good, I do not consider this scenario inevitable (though relatively likely), and I would expect general AI to present an existential risk even if I knew for sure that intelligence explosion were impossible.
