Robin Hanson on Friendly AI:

I’m also not big on friendly AI, but my position differs somewhat. I’m pretty skeptical about a very local hard takeoff scenario, where within a month one unnoticed machine in a basement takes over a world like ours. And even given on such a scenario the chance that its creators could constraint it greatly via a provably friendly design seems remote. And the chance such constraint comes from a small team that is secretive to avoid assisting wreckless others seems even more remote.

[...] I just see little point anytime soon in trying to coordinate to prevent such an outcome.
