If I wasn't a professional scientist, I'd be an amateur scientist. But plan B was to go into computers.

Consciousness-one level is understanding where we are in space. Consciousness two is where we understand our position in society: who's top dog, who's underdog and who's in the middle. And type-three consciousness is simulating the future. And type-three consciousness, only humans have this ability to see far into the future.

To me, it is clear that we exist in a plan which is governed by rules that were created, shaped by a universal intelligence and not by chance.

No one knows when a robot will approach human intelligence, but I suspect it will be late in the 21st century. Will they be dangerous? Possibly. So I suggest we put a chip in their brain to shut them off if they have murderous thoughts.
