Heh. I had exactly the same response: it didn't sound like Chomsky to me. I even commented to that effect, but then had second thoughts and deleted it. It wouldn't be unnatural to use a different voice in a casual email than in a published article. Also, some of the things in there do sound distinctively like Chomsky (e.g. the second last paragraph).

I searched around for more on Chomsky and postmodernism and came up with http://archive.zcommunications.org/chomchatarch.htm, which includes quotes from the OP. So it seems it's at least partially authentic.

As for whether he would have had time, that's easy. It's already impossible to explain how he has time to do what he does.

Edit: I also ran across a clip of Chomsky's discussion with Foucault on Dutch TV from the early 70s (http://www.youtube.com/watch?v=kawGakdNoT0), which was fun to take a look at. Can you imagine anything more un-TV-like? The very length of their sentences is unthinkable - I was going to say "nowadays" but I bet it was unthinkable on TV even then.
