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.

In Spring 2012 Luke Muehlhauser asked Kaj Sotala to write a summary and analysis of the debate; he made a draft of that analysis available in November 2012. The final version of the summary is included in the ebook.
