alt Hacker NewsFun fact: 80% of the brain's neurons are in the cerebellum, not the cortex.
In other words: only <20% of pur neuron budget goes to higher cognition (thinking, language, seeing, hearing). 80% is spent on motor skills.

Oh, so Moravec’s Paradox is not really a paradox, it’s just an illusion! ;-)

The cerebellum isn't just for motor skills. It's more of a place where very commonly used patterns get a bunch of dedicated wetware so the computation is superfast and precise. In an (undoubtedly very limited) analogy a bunch of FPGAs to complement the general processing. It does make a lot of sense to use this functionality for motor skills, though.
