The BBC has an article about how Eric Horvitz (director of Microsoft Research's main lab) doesn't think AI poses a big threat to humanity.

Not a very high-quality article, though. A few paragraphs about how Horvitz thinks AI will be very useful and not dangerous, a few more paragraphs about how various other people think AI could pose a huge threat, a few kinda-irrelevant paragraphs about how Horvitz thinks AI might pose a bit of a threat to privacy or maybe help with it instead, the end.

Apparently Horvitz's comments are from a video he's made after getting the Feigenbaum Prize for AI work. I haven't looked at that yet; I suspect it's much more informative than the BBC article.
