Long over due.
Most teachers and even in a college/university, they do not really teach.
They get handed a curricula, textbook, workbook, online framework to use... Everything they do is scripted and they are no more than a highly paid presenter where on rare occasion if asked a question and someone needs help they can actually reach back to their own knowledge... You already have this automated assembly line education system. Most of these educators do not have the time to individually do much for those they are instructing (student to kid ratio, too many classes and not enough grading/conference periods, bogged down with massive admin burdens to CYA everything).
All you’ll do by automating it completely is remove the face of a teacher that in most cases cannot actually help anyway.
That is true in Houston, TX. HISD will only accept applicants with “education degrees”. They will refuse any retired engineer or scientist, and Houston has plenty of engineers and scientists with the energy industry and NASA. The reason - The teacher is supposed to follow the script, no deviation, no illustrations of real world example based on his or her experience (except maybe leftist politics). No real subject matter experts (as in those with real world experience).
As for college, I was lucky. Many of my professors were retired engineers who were still doing consulting work on the side.
