Quote of the day

I have to say I love this quote:

[T]he Stone Age did not end because we ran out of stones. It ended because it was time for a re-think about how we live.

It's ascribed to architect William McDonough by this BBC article, which describes new trends in city-building being tried out in China. I usually am skeptical of futurists because they tend to get the past wrong, and this quote certainly isn't quite right -- don't know that Bronze-Agers were really doing a "re-think." But it's a million-dollar analogy.
