“Can all this just be an accident? Or could there be some alien intelligence behind it?”

“Intelligence is an accident of evolution, and not necessarily an advantage.”

“Quality is never an accident; it is always the result of intelligent effort.”

“You should only alienate folks when you mean and want to do it. […] It should never be an accident.”

“It happens fast for some people and slow for some, accidents or gravity, but we all end up mutilated.”

“Intelligence is ongoing, individual adaptability. Adaptations that an intelligent species may make in a single generation, other species make over many generations of selective breeding and selective dying. Yet intelligence is demanding. If it is misdirected by accident or by intent, it can foster its own orgies of breeding and dying.”

“Quality is never an accident. It is always the result of intelligent effort. There must be the will to produce a superior thing.”

“Martin: It’s alright. It’s fun, and all the spray’s behind you until you’re behind another car. It’s aquaplaning that scares the life out of you, when the car gets up on top of the water and you’re temporarily not in contact with the ground and you can head straight to the scene of the accident with the silliest little move of the steering wheel.”

“They’d lived all their life on Earth; they knew nothing but the Earth. They had never really touched an alien concept, and that was all this concept was. It was not really as slimy as it seemed. It was only alien. There were a lot of alien things that could make one’s hair stand up on end while in their proper alien context they were fairly ordinary.”

“Let an ultraintelligent machine be defined as a machine that can far surpass all the intellectual activities of any man however clever. Since the design of machines is one of these intellectual activities, an ultraintelligent machine could design even better machines; there would then unquestionably be an "intelligence explosion", and the intelligence of man would be left far behind. Thus the first ultraintelligent machine is the last invention that man need ever make.”
