Alien, I mean really Alien.

Dogscoff, what your saying is that they may develop a fear reaction, but they won't be feeling fear?

Well, if it serves the same purpose as fear, and it provokes the same response as fear... why don't we just call it fear? There will undoubtedly be biological differences but the end result is the same. After all, how do i know that when *you* feel fear you feel the same thing as me? How do I know you don't see red as what I would call call blue?

It's like the Turing test for AI: You can't know for sure whether a machine is actually intelligent or just doing a really good impression of one that is, but when it gets to that stage there's very little point trying to tell the difference anyway.
