My thought experiment question around Psychiatry is: How would pre-electricity age people explain the operations of a digital computer? They would probably invent some theories that bore no resemblance to the actual underlying technology. They might be close and even create some relevant metaphors but the theory would never be "correct", I suspect. Is this analogous to Psychiatry?

An old engineering axiom is: "If you can't build it, you don't really understand it"

This leads me to ask, will we only understand the human mind after we learn how to build one or two?

Notwithstanding the question, can a network with X neurons fully comprehend a network with X neurons?
