“Future Progress in Artificial Intelligence: A Survey of Expert Opinion” (2014) reports a survey result (Müller and Bostrom, survey of expert opinion): “systems will move on to superintelligence”; horizon as stated: in less than 30 years thereafter (after high-level machine intelligence); the question asked for probabilities "within (2 years / 30 years) thereafter". The record says nothing about whether the event happened.

One recorded claim. The claim panel gives its qualification, the source passages with their place in each source, and how it was checked.
