Thank you for the link! I was actually wanting to read a survey on this topic. I'm obviously sympathetic with the general approach of focusing on augmenting rather than replacing humans in teaching.

I confess I'm more skeptical of "data, data, and more data" than the author (from whence it comes? an A/B test of the video widget we wrote last week? the "anecdotes" of a skilled teacher with decades of experience can surely be more informative sometimes!), but I'm certainly eager to incorporate what good data is available!
