A brain itself might be a guessing machine it's an established and actively studied research model of the human thought and the human brain.

Nor does knee jerk accusation of "anthropomorphizing" negate the fact that procedures that mimic human processing, even when done in software, are deservingly anthropomorphized, because they're a legitimate approximation of the human equivalent operations.

It's not a new revelation, but clearly a lot of people aren't aware of it, so talking about it is still valuable.
