When I was in the 10th grade - way, way back in time, like decades - I knew a guy, Robert Fulton, who one afternoon tried to teach me the difference between Basic and Fortran codes. Ha!  I still have no idea how to code anything.  But I’ve been smart enough to have figured out that people who code are precious cargo, and true code ninjas, a name I bestow upon them with much reverence - the people at the top of this game - are true rock stars.  The creme a la creme are hard to find in the Midwest:  there are people who code, and there are ninjas.  But in California, and in Ivy League dorm rooms, ninjas are everywhere, and they start companies like Microsoft, Facebook, Dropbox, and most recently, SnapChat.  This video was posted yesterday, and it has already 2 million views.  Good God.  I look back at all the classes I took at a very good university and shake my head at how unimportant most of them were in the context of optimal teaching in terms of bringing home a lot of bacon, or changing the world, or both.
