I have a different theory.

Aside from a few exceptions like Blake Lemoine few people seem to really act as if they believe A.I. is doing the same thing the human mind is doing.

My theory is people are for some reason role-playing as people who believe human thought is equivalent to A.I. for undisclosed reasons they themselves may or may not understand. They do not actually believe their own arguments.
