Invasion of the Robot Teachers

The (political) reason for compulsory education is to prepare young people to enter the work force. At the point that a robot is equivalent to a human teacher, doesn't that indicate that the singularity is upon us and almost all work can be performed as well or better by machines?

Considering that this is posted on "singularityhub," I am surprised that they did not address this possibility.

Of course, the fact that these current robots seem more a novelty than some significant improvement in education might have something to do with that oversight.

... that's sarcasm, right? I sure hope it is.
