One of the interesting discussions I read was how much more energy efficient the human brain is compared to today's AI chips. So, if science learns to process information with the same energy efficiency as the human brain, do you still think AI is at a dead end. This article talks to the issue, but I can't remember where I first came across how energy efficient the human brain is.
