This is a great discussion about whether AI (1) is currently sentient and (2) can, in principle, be sentient. All three panelists agree that it not currently sentient. It is 2 to 1 on whether it can, in principle, be sentient. As you might expect, how the materialists reach their conclusion follows more from metaphysical commitments than evidence. Max and Melanie (the materialists) see no reason why, in principle, computers cannot in the future be conscious. Why not? they ask, we are all just material stuff. And if you agree with their metaphysical premises, that is an unanswerable question. Max, especially is committed to this view and thinks we should be more humble. He is so blinkered by his commitment to materialism that it does not seem to occur to him that there can be any possible reason to think machines cannot be conscious other than arrogance.
Bob is a dualist and reaches the opposite conclusion, and he gives some excellent reasons to question materialist premises. I commend this excellent discussion to you.
BTW, Bob Marks really knows his stuff, and he presents his arguments in a very winsome fashion. We should all follow his example.
