Thanks in part to the popularity of his books, movie, and speeches, Kurzweil now knows pretty much every AI researcher in the planet, and we can safely assume he's aware of even very obscure research projects in the field, both inside and outside academia. Joining Google gives him ready access to data sets of almost unimaginable size, as well as unparalleled infrastructure and skills for handling such large data sets…
I just can't see Kurzweil being in the same league as Peter Norvig. Sure, he did some interesting work a long time ago, before he got weird. I can't see this working out well for Google, unless they just want a famous figurehead.
He was weird then too. That's why he did such interesting work. His work, combined with a lack of fame at that time, just kept the weird from showing through.
I suspect that genius is made up almost, but not quite, entirely of crazy.
