They are smart, they have money, and they predict the Super AI Doomsday:

Stephen Hawking
"The development of full artificial intelligence could spell the end of the human race”

James Lovelock
"Before the end of this century, robots will have taken over"

Nick Bostrom
"Some little idiot is bound to press the ignite button just to see what happens."

Elon Musk
"Artificial intelligence is our biggest existential threat"

So, obviously, +1 points for the Singularity to take off.
