In late 2008, an extensive and long-awaited debate about the Technological Singularity occurred on Overcoming Bias, mainly between Robin Hanson and Eliezer Yudkowsky. It focused on the likelihood of hard AI takeoff ("FOOM"), the need for a theory of Friendliness, and the future of AGI, whole brain emulation, and recursive self-improvement in general. A stand-up debate on the same themes took place at Jane Street Capital in June 2011, and Hanson made a further post in 2014.
