The electrical theory of the brain has already failed:
"some AI researchers have simulated the entire, already-mapped nervous system (302 neurons) of the tiny worm C elegans. Like paramecium, we don’t know if they’re conscious, but C elegans clearly exhibits ‘easy problem’ behaviors, e.g. moving in response to stimuli. But even artificial C elegans just sits there, with no functional behavior. AI can’t simulate the ‘easy problems’ in simple brains. Something is missing."

"Something is missing. Therefor God" I don't understand it, therefor God" Religious people always take the easy way out instead of investigating
