My view on the singularity - in terms of the technological possibility space - is largely consistent with my previous thoughts. Replacement organs will be commonplace in the 2020s (and I think robotic replacements too) and nanotechnology/even more intense robotic revolution will be 2030s. By the 2040s our technological capability will be beyond anything we can reasonably expect to understand by contemporary standards. What is changing is my views on the social, cultural, and political ramifications. I have actually spent the last year writing a paper (about 70 pages) with everything I currently think about the evolution of the universe and the 21st century. One of the final working versions before official publication in Foundations of Science will be up probably this month or next month.
