• During one of his messages, Peter Denning showed the familiar quote, “Insanity is doing the same thing over again, expecting different results,” as a motivation to change.

I was reminded of a recent Frazz comic, in which the precocious Caulfield pointed out that the world is always changing, so it is also insanity to do the same thing over again, expecting the same results. The world is changing around computing and computing education. There is no particular reason to think that doing the same old things better will get us anywhere useful.
