The ability to test depends entirely on my familiarity with the human and 
how good the technology is. Can I touch them, smell them? If so, then I 
would be surprised if I could be fooled by an inorganic body. Has there 
ever been one synthetic imitation of a natural biological product that can 
withstand even moderate examination?

If you limit the channel of my interaction with the robot however, I stand 
much less of a chance of being able to tell the difference. A video 
conference with the robot only requires that they look convincing on 
camera. We can't tell the difference between a live performance and a taped 
performance unless there is some clue in the content. That is because we 
aren't literally present so we are only dealing with a narrow channel of 
sense experience to begin with.

In any case, what does being able to tell from the outside have to do with 
whether or not the thing feels? If it is designed by experts to fool other 
people into thinking that it is alive, then so what if it succeeds at 
fooling everyone? Something can't fool itself into thinking that it is
