The Mu philosophy:
Less is more (remove all unnecessary distractions);
Keep it simple (so Mu is easy to understand);
Walk the path of least resistance (Mu should be easy);
Have fun (learning should be a positive experience).

What that future is depends upon who turns up to provide such education.
Don't just sit there, do something!
