Via The Valve, the IEEE has a special issue on The Singularity. Ray Kurzweil and Neil Gershenfeld discuss 
“Two Paths to the Singularity” can be found here. The views of some prominent computer scientists, biologists and all-around smart people such as T.J Rogers, Gordon Moore and Steven Pinker can be found here. Pinker:
WHO HE IS Professor of psychology at Harvard; previously taught in the department of Brain and Cognitive Sciences at MIT, with much of his research addressing language development. Writes best sellers about the way the brain works, like The Blank Slate (2002) and The Stuff of Thought (2007).
SINGULARITY WILL OCCUR Never, ever
MACHINE CONSCIOUSNESS WILL OCCUR “In one sense—information routing—they already have. In the other sense—first-person experience—we’ll never know.”
MOORE’S LAW WILL CONTINUE FOR 10 more years
THOUGHTS “There is not the slightest reason to believe in a coming singularity. The fact that you can visualize a future in your imagination is not evidence that it is likely or even possible. Look at domed cities, jet-pack commuting, underwater cities, mile-high buildings, and nuclear-powered automobiles—all staples of futuristic fantasies when I was a child that have never arrived. Sheer processing power is not a pixie dust that magically solves all your problems.”
