Scott Aaronson is not a quantum-computing skeptic, quite the opposite, he has always seemed optimistic about its prospects and his work has been fundamental to progress in the field. He just does not like hyped-up work that has little substance. If anything, Bruce Schneier should have been a bit more skeptical - this type hyped-up unreviewed preprint papers appear very frequently these days.

I think he was fairly skeptical but said the proof would come when someone tries to implement it; he now links to Aaronson's take in his original blog post.
