Once again Richard Wells nails the reality of the world our students are in (and that education has yet to catch up to).

The graph below depicts calculations per second capable on a single computer in each year since 1940.

Preparing for exponential change is difficult because of its two phases. Phase one: Today looks just like yesterday; Phase two: What’s going on? If you compare current developments we are experiencing in phase two, phase one made life in 1940 and 2005 essentially the same.

You can understand these two phases if you just take a moment to…
