As someone who has done research in the field, did you read the Gizmodo review of Siri?

The set of "knowledge graph" problems which is not, in fact, AI-complete, strikes me as much smaller than most doing research in the field would like us to think.
I hope you won't try to argue that "book me a room" etc. isn't AI-complete. There's an uncanny valley there, and it's deep. You can use Siri for lots of trivial tasks in which bizarre failures are hilarious rather than disastrous, but booking hotel rooms isn't in that set. She can be the best secretary in the world 9 times out of 10 or even 99 out of a 100, but the other times she's an insane robot who wouldn't at all mind sending you to Cebu to get kidnapped by the MILF...
