I read one of the conclusion: "Lastly, I can't imagine that tech won't win here with non-human based teaching. It's affordable, convenient, and scalable to any genre, language, right from home on many platforms."

I strongly disagree with that one. The pie is big enough for different type of teaching, including real-life classes.

If what he predicts turn out true, and we all get plugged behind screens to learn new things... what a sad world it would be...
