“It should be obvious that technologies are capable of replacing teachers and professors in a wide variety of settings. The current buzzword for this is the flipped classroom—students watch lectures and learn the material online at home, then do their homework at school with the help of teachers and teaching assistants. Teachers may no longer need to prepare or deliver lectures, reducing them to what could be called “learning coaches.” The diminished skill set required is sure to transform the profession and create yet more challenges for our already beleaguered teachers.”
