My attitude toward automated teaching is the same as my attitude toward automated cars: you won't beat the best humans (in the near future), but you'll probably rival or beat the average humans (mediocre training, tired, grumpy, etc.)

I had enough teachers who were barely able to grasp the material themselves, vindictive, or emotionally unfulfilled in their personal lives, that I'd rather have learned from a book, computer, and videos. But hey, maybe dealing with crazy or incompetent educators is an important socialization step for young people...
