We have actually little idea how human brains work.

Every age thinks they know how they work, and then every subsequent age laughs at the previous age’s rudimentary understanding.

We gave a Nobel prize to the psychiatrist for inventing a method to remove the frontal lobes of a brain through the nose in 1949. Lobotomies were performed through the 70s.

We are likely doing similar if not subtler but worse things today (just one more pill bro). We still have no idea what we are doing when it comes to the brain.
