If you can't tell if your AI friend is real, are they not a real friend? They might not be human, but they will still be your friend, no?

I think they meant: are you really talking to your friend the human, and not a bot impersonating that friend.

But then you would need to shoot them to see if they bleed or not.

And claw at your own eyes to make sure you are not in a VR :)

Nah because with everyone using AR, Google Glass, and Snapchat spectacles, we won't even be able to trust what we're seeing isn't manipulated.

It's already happening, most people I know rarely, if ever, answer calls from unknown phone numbers.
