What will replace k-12 and college?

A Three-Phase, Rational System of Education
I don’t know just how or how fast the change will happen, but I think the days of K-12 and four years of college are numbered and sanity will begin to prevail in the educational world. I envision a future with something like the following three-phase approach to education:

Phase I. Discovery: Learning about your world, your self, and how the two fit together.
Phase II. Exploring a career path.
Phase III. Becoming credentialed for specialized work.
