2. Hope that some of those students become teachers after their tertiary education where programming is included. Now you have 8 year olds being competently taught how to program.

4. Government decides that all kids should learn to tinker with arduino.
My point is: not all kids needs to learn to program, only to know that it is something they might be interested in.
