> 2. those who believe that sentience is human-only and that a machine can't be sentient, no matter how sentient it appears
Why stop there? There's no reason some humans couldn't be non-sentient, no matter how sentient they appear.
What possible test can you conduct to determine whether someone has subjective internal experience? I don't think it's possible. I think we just have to take people at their word: if they say they're sentient, we have to believe them. I don't see why machines should be held to a higher standard than humans.
