You may have heard the old joke, if you've been to IRC in the past. It goes something like this. Two old buddies are alone in a chatroom. It seems they've run everyone off. Then, one of them slips up. The other one does a double-take, and says, My god... You're a robot. And the other one confesses or destroys the human in multiple variations of this joke.
Eventually, you get used to the joke, and people never question each other's humanity. My questions follow.
1) Why do we forget to question? What if our "friends" are AI's?
2) What questions would we ask if we suspected a user was a bot?
3) How comfortable are we sharing a world online with robots?
4) Is the Internet itself a robot?
5) Are we bots, and we don't know it?
Or maybe we have no questions to ask. Maybe we need to look only into the cosmos of our friends minds. Inside...
The Fractal
We've concluded, then, it is unnecessary to wonder that our friends are (not) robots.
