Even if machines eventually acquire a form of consciousness, how would *we* know? Who would believe a machine's claim to be conscious?
Well, you can't really prove you're conscious. I don't even mean proving it to me, I mean you can't prove it to yourself.
What if every decision you make is made before you realize it? What if what you think of as consciousness, what you think of as your decision making process, is merely a byproduct of packaging that decision up for dissemination to other parts of your brain that need to know about it, but weren't involved in the making of the decision. Maybe you didn't even make the decision for the reasons you think you've made it. You think you decided to get the high deductible insurance over the low deduction insurance because you have enough money saved up to pay the deductible if you have to, so paying a smaller monthly premium makes sense. In reality, your brain structure is wired up to prefer lower payments, and you would have made that decision whether you had the money available to pay for the deductible or not. In fact, you did make the decision immediately, but as your brain was packaging up that information, it consolidated it with other related facts you knew, like how much money you have saved up. That information happens to mesh with the decision that was made completely independently from "you", as you think of yourself, from your "consciousness." So it justifies the decision, and that wiring on your brain thinks it's now MAKING that decision as a result of it. If, in fact, you didn't have enough money to cover the deductible, you would have made the same decision, because the decision was already made, and simply have filed that information on the cons column of what you *think* is your decision-making process, but is really just a filing operation.
There's really no way for you tell the difference between your being conscious vs. a purely deterministic computation that has the side-effect of treating a high-level summary of a complex process as the actual driving component of all the process. I personally believe that's actually what happens, because otherwise it requires us to invent this weird concept of consciousness which nobody has a good strong definition for.
