Ned Block covers this in his paper on the Harder Problem of Consciousness. Other humans share a similar biology, so we have good enough justification to think they're conscious. It won't defeat solipsism, but it's enough to make a reasonable assumption. Data or whatever AI/Android doesn't share our biology. And since we can't tell whether it's the functioning of our biology or the biology itself which provides us with consciousness, we lack any reasonable justification for assuming Data is conscious. And then he goes further into functional isomorphs at different levels and how that might or might not matter for Data, but we can't tell.

> Other humans share a similar biology, so we have good enough justification to think they're conscious. That's the way it goes with these arguments: it always comes down to an appeal to what's reasonable or plausible (those who insist consciousness must be an algorithm are doing the same thing, at least until we have algorithms that seem to be making some progress on the hard problem.) One might equally say other humans share a similar physics. When Dennett said "we are all p-zombies", I suspect he was making the point that it would be highly tendentious to take the position that anything both behaving and functioning physically in the manner of a human would not be conscious, except for humans themselves.

I see a lot of resemblance in biology between myself and cats, does that mean that cats have qualia? I infer they dream from their twitches as they sleep. How about mice? Lizards? Fish? Insects? Nematodes? At what point do qualia stop occurring? I see a more or less continuous decline in similarity. I don't see any justification for a cut-off. I don't think data is conscious. I suspect consciousness might be a side-effect physical computation. I don't believe there's any magic to the human brain's inputs and outputs which cannot be computed, and thus display the appearance of consciousness. In fact I see the Turing test as a thought experiment more than any actual test, a way of removing the appearance of a human body from the task of evaluating an artificial intelligence as a thinking, conscious being. If it quacks like a duck, a rose by any other name, etc. In fact I'm not entirely convinced that the Western conception of consciousness isn't a learned cultural artifact, that there aren't people who have a more expansive notion of self which includes close family, for example. Have you ever suffered watching a relative hurt themselves? Ever had false memories of injury from childhood which you found out later happened to someone else?
