Teachers who focus more on imparting factual knowledge are becoming less and less relevant. 

A few who are great at it can reach millions via the Internet and achieve better results for those learning than what they can gain in a classroom with a less able teacher.

Teachers who focus more on getting their students to see in a new way, to gain perspective, are as relevant as ever.

This is emotional labour that doesn't scale.

At least, not until the Large Language Models have their say.
