Can they build a computer faster than the human brain?

A computer that outsmarts the human brain will be built within a few decades, gores the claim.  It's in the 'Did You Know?' video http://www.youtube.com/watch?v=cL9Wu2kWwSY&feature=related, about the rapidly expanding pace of technology.  Here's a rational, scientific perspective on that claim from today's New York Times.

An intriguing discussion of how amazing the brain is - uses 12 watts of power, less than half that of a laptop, and it might be estimated to have a storage capacity of 1 petabyte (1 X 10E19) bytes.  But also, that it works well, makes judgments and has emotions despite having faulty components that don't always fire when they're supposed to.
