What seems to be the consensus is that academia has not brought in any revolutionary innovation for decades. Whenever practical innovation came, it came from characters as far from the 'standard intellectual stereotype' as could possibly be. As a result there is a haughty "keep debating while we get the job done" attitude, which may be mistaken for anti-intellectualism. In reality it is not that geeks dislike experts and intellectuals - it is that they've met too many would-be-experts who failed their most trivial relevancy tests, so the term 'expert' raises a BullshitIncomingException almost immediately in any geek's mind.
