It's a very strange statement indeed to claim that there's nothing built-in for it. We built it around / within our capabilities. It works so well precisely because we built it for ourselves, for what we are capable of.

It's almost like they're pretending it spontaneously came from nature (or always existed absent of humans and we discovered it) and we weren't evolved for it but somehow adapted to it. You could insert eg a bicycle into the same premise: we ride them absurdly well given there's nothing built into the brain for specifically riding a bicycle (except there is: balance, grasping acceleration, etc. - we designed them for our use just as we did text).
