The Course of Empire

In a blog post titled "Evolution of every medium" Seth Godin makes an observation that, based on my experience, feels right but—as with researchers who find evolutionary imperatives for various human behaviors, such as shopping—there is no way to actually test his assertion.

(While we're at it, I'm hoping someone can explain why that branch of "science" is taken seriously, since it is immune to the rigors of the scientific method.)
