The two major functions of education are inheritance and teaching.

Inheriting and innovating human civilization, we call it cultural education, learning history and culture.

Teaching and developing human technology, we call it technical education and learning professional technology.

Teaching and developing human technology, for ordinary educatees, is to enable them to master certain technologies, serve and support society, and at the same time support themselves and develop themselves through education and training.

But it is not the whole or even the most important part of education. The most important part is to inherit and develop human civilization. Only such education can educate educators into adults, not tools.
