Sabine Hossenfelder, Nick Lane, and Yoshua Bengio debate the physics and biology of consciousness, and whether this could lead to the creation of a sentient artificial intelligence.
What was the evolutionary origin of consciousness?

It is seventy years since the pioneer of computer science and Enigma codebreaker, Alan Turing, argued that if we cannot distinguish between a computer's response and a human's, the computer is intelligent and can be said to think. According to this Turing Test computers are already thinking and intelligent. But critics argue this is a nonsense, and that it remains unknown how to test for intelligence or consciousness. The computer they argue is nothing but a machine able to produce outputs that copy human responses but it does not understand these outputs or have any intent in producing them.
Should we conclude that thought and consciousness are unobservable, and there is no brain process or computer test that identifies them? Was the Turing Test in fact a highly successful rhetorical device to encourage us to conclude that machines might one day think, now embedded in the very name 'Artificial Intelligence'? Or is this misguided and computers are already thinking beings and a modified version of The Turing Test can provide a test for consciousness?
