Joscha Bach says a current chess computer's algorithm could not be implemented in human brain neurons because it could not be trained into them.

“The chess algorithm that runs on a cur-current chess computer could not be implemented on the neurons of your brain, because how would you entrain it on these neurons?”

“So you wouldn't get it in there. In order to entrain yourself to play chess, you need to have a conscious human being. It's the only way in which a human being is train-training itself up there.”
