Did anyone actually say that superhuman machine intelligence is prima facie ridiculous? I followed the discussion pretty closely, both on hackernews and the quotes and discussion by prominent researchers, and I don't remember reading that. It's possible that one or two people somewhere in the discussion said the idea was completely ridiculous, but it didn't seem to be the common sentiment. The main dissenting ideas I saw said that it was too far away to be considered as a threat, and that most high profile researchers weren't giving it serious consideration. I don't doubt that "otherwise smart people" have said that superhuman machine intelligence is completely improbable, but I don't know about the "many" part. There's always someone who will say anything. The closest I've seen to a consensus is disputing the timeframe for AGI/SMI, not the possibility. For that matter, I don't remember seeing a lot of people say "Computers will never play chess" or "Computers could never drive cars" or "Computers could never compete on Jeopardy". I can't recall one prominent researcher saying any of those things definitively, much less "many" people saying any of them. It seems like there might be some inserting of quotations into the mouths of others going on here.
