Nice points. I have two kids under 6 right now and was starting to worry about how smart phones might replace computers for most of what they do and thus never expose them to an easy to program platform. What's really exciting for them is the abundance of hobbyist computers and embedded project kits available now. They're going to grow up in a world where simple microcontroller-style projects are completely accessible to them. Makes me almost want to be 6 again!
Millennials can still catch up, but I think the next generation is the one that's really going to be primed to do amazing things.
