The kids remember it forever.

No they don’t. Really, ask yourself how much of what you were taught through high school you really remember. Not can dredge up if given a bit, but really immediately answer a question. The truth is probably very little, because it’s not data you access all the time, your brain’s got more important things in there. Probably math, there’s lots of algebra in cooking, and bill paying and some other parts of normal life. The basic English language skills obviously, but the books you were forced to read probably not. Outside of that it’s background noise in your brain you dredge while watching game shows or chatting on FR.
And truth is these boxes we’re sitting in front of make it worse. The more we learn we can just go GET data the less we store. Nobody remembers phonenumbers anymore, they punch them in the cellphone. If you can’t make your brain store 7 numbers you actually intend to use think of how much harder it is to store data that’s just “nice to have”.
