Rubbish.
Numbers 1 and 3 are addressed by neural network theory which, even though it’s been around since the 19th century, it appears Dr. Egnor has never heard of. It’s no accident that this is a fundamental aspect of AI research:
Number 2 is just silly. Cutting the corpus callosum is NOT the same thing as “cutting your brain in half”. It is simply bisecting a particular bundle of connecting fibres. That this has limited effect only demonstrates that the hemispheres of the brain largely function autonomously from one another.
Maybe I’ll watch more and comment later. I’m working, and also the Raptors’ victory parade is on today!
