All of this is so far from anything evolution would have selected for that we can pick our favorite argument: 'well humans are unique in our tool use, so we should be encouraging kids to learn new tools instead of explicit teaching (like montessori)' or 'well humans never learned to read until about 100 years ago and computers can read for us so don't teach this new-fangled reading stuff'
It's not a helpful frame. The language thing is totally distinct—that really is an innate human thing among children. So again we can't make useful evolution-based claims about adult language education.
"we evolved to remember what happened to us, not to learn history of countries on the opposite side of the planet"
this argument doesn't work. if you want to claim harm - talk about the harm directly. stop hiding behind "evolution" and "biological"
