Attachment to a leader and/or parent seems to be a deep part of human personality. Especially in the first decade or two of life. I suppose a teacher-at-the-front could be replaced by a soft robot. But that's not a really large change in the method of education.

I do remember when learning calculus that I didn't really know integration and differentiation until I'd worked through a dozen or two of the homework problems. I could understand in class and nod my head, but would not be able to use that knowledge until I'd ground through enough example problems. That paradigm seems to be true for a lot of technical subjects and must be a result of the nature of human cognition.

And the world is getting even more scientific, more technological and more mathematical.

And those who teach writing emphasize that it is necessary to write a lot. A whole lot.

Recently popular has been the idea that to master any subject whatever requires 10,000 hours of practice. That idea has been attacked and taken down a peg, but not defeated; practice alone is never enough.
