While all of what you say is true, we simply cannot teach everything since there is just too much knowledge and too little time in a human life.

And not everyone is equally interested or capable in learning everything.

This is necessarily the world we live in, even without adding capitalism or any evil intentions to the mix. Any education you can get or offer can only be a more or less well selected subset of the knowledge available.

In this light, I don't see it as a dramatic loss to remove educational emphasis from skills which can easily be replaced with modern technology. It would make sense to shift the focus to teaching a critical usage of said technology.
