Comment by Houshalter

The fact they aren't concerned is exactly the problem. They should be. And in fact many are. See the SSC link posted below (http://slatestarcodex.com/2015/05/22/ai-researchers-on-ai-ri...), or this survey (http://www.nickbostrom.com/papers/survey.pdf). Certainly I am worried about it. There is far from "uniform agreement" that AI is safe. And appeals to authority would not comforting even if there was an authority to appeal to.
