Well, still, his argument isn't that London / Europe today are just as good as Silicon Valley, his argument seems to be to stop telling people Silicon Valley is better because they'll go there and Europe won't be able to catch up... in effect, that Europe CAN be as effective as Silicon Valley if nurtured. But that simply agrees with pg's argument that today, Silicon Valley is a better destination.
