Perhaps brain plasticity has its own downsides. Otherwise, why evolution would make us lose a lot of it once we reach adulthood? If there was no downsides, keeping a plastic brain for the whole life would be very adaptive. A gotcha must hide somewhere here.

I think a lot of learning was necessary to map and adjust to new territories. So, I'm not so sure potential maladaptative learning explains everything.
