> because we don’t have one yet

Part of the problem is that at this point we have no way of ever knowing if something is conscious or not. We assume that other humans are because they look like me, act like me, and are made of the same stuff; and I know that I am. But all I really have is your word that you are. Will that be enough from a computer? I can write a program right now that says it’s conscious, but it wouldn’t be. So how can we ever know?
