"You could also, if you had a sufficiently good understanding of organic biology and aerodynamics, build an airplane that could mate with birds. I don't think this would have been a smart thing for the Wright Brothers to try to do in the early days."
— Eliezer, in this interview with John Horgan, when asked whether AIs will experience sexual desire

"As you know, birds do not have sexual organs because they would interfere with flight. In fact, this was the big breakthrough for the Wright Brothers. They were watching birds one day, trying to figure out how to get their crude machine to fly, when suddenly it dawned on Wilbur. "Orville," he said, "all we have to do is remove the sexual organs!" You should have seen their original design."
— Dave Barry, "Sex and the Single Amoeba" (1986)
