according to J-P Serre. I spent an hour watching this video of his talk. Considering I may never have the chance to meet him in person, this was not a bad way to spend Saturday morning. It is accessible to a general audience although you probably need to know some homological algebra, analytic number theory and other stuff to appreciate the points he was trying to convey.
I first saw the link via Steve’s weblog although many sites are also carrying the link. Not surprising since there are so many mathematicians blogging now, including Terry Tao and Alain Connes. Read this nice post by Steve.
No time to spare? This article by David Goss, which incorporates hints from Serre, contain a few of the points highlighted in the talk. In trying to link it, I discovered this version was updated Feb 2007.
