Suicidal terrorists are hardly a threat to the existence of humanity. It takes quite a bit more than explosive vests to destroy all of mankind.

All of it, sure. But most of it might be easier than you think. Just one bomb in the wrong place can trigger a chain of catastrophic events. Don't forget that we have nukes in places like North Korea and Pakistan, and Iran is building one as fast as they can.

Excuse me, but I'd rather worry about those threats, than about a robot uprising.
