It is less "computation" and more "pattern matching/processing", something computers are really bad at, but people are relatively good at.

How is pattern matching not computation? The fact that you don't notice the underlying computational complexity is just a measure of how freaking good humans are at pattern matching.

It is true, at its core it is a form of computation. Though it blurs the line a little- the human brain isn't exactly pushing around numbers.

to be fair your computer isn't exactly pushing around numbers either. your computer does the same thing your nervous system does: push around electrical signals.
