Peter Thiel explains why aliens with faster-than-light travel must be demons or angels: only a demonic totalitarian mind meld or perfect angelic altruism could keep any one of them from launching a warp drive weapon "...If you have faster than light travel, if you have a warp drive, which is probably what you really need to cover interstellar distances, you know, what that means for military technology is that you can send weapons at warp speed and they will hit you before you see them coming. And there is no defense against a warp speed weapon." "And so it tells us that I think that if you have faster than light travel, there's something really crazy that has to be true on a cultural, political, social level. And there may be other solutions, but I'll give you my two." "You have a demonic totalitarian control of your society, where it's like you have like parapsychological mind meld with everybody, and no one can act independently of anybody else. No one can ever launch a warp drive weapon." "And then I think the other version, socially and culturally, is they have to be like perfectly altruistic, non-self-interest. They have to be angels." "It's not that they might be demons or angels, they must be demons or angels if you have faster than light travel. And both of those seem pretty crazy to me."

Listening to this whole interview and these comments in context you see he is actually making a pretty nuanced point. You can criticize him all u want but taking clips out of context to manufacture outrage is so lame— critique what he actually said!
