Today is Labor Day. That means that tomorrow NYC public school teachers return to work. I mean, not me - I'm still happily retired but still I have many friends going back. Kids come back on Thursday. Of course, I don't doubt that I'll have a "going back to school" dream tonight. I'm not going to make any predictions here but there are a couple of big tech related elephants in the room that will be interesting to keep tabs on over the course of the school year.
