Understanding how things work so you can work with them and make them work for you matters. Learning most of this stuff takes place in real-life experience, not in classrooms. Schools might be obsolete. Today's multimillion dollar classroom buildings may be tomorrow's educational museums or homeless shelters. Where you learn doesn't matter.
People can learn anywhere and everywhere.
We already do. Most of the stuff that makes you a valuable worker you learned on the job. Home schooling is a clue. Students have almost nothing to say about the content or quality of the schooling they pay for. For their tuition, you'd think they would get the ability to thrive in their chosen profession, yet they don't.
