Drucker on 'tribes'

During the coffee-break this morning, I serendipitiously ran across a printed paper of Peter Drucker, in which I found this quote that I like. To a journalist who asked "What will the organization of tomorrow and the executive of tomorrow look like?"

"You'd better stop studying the history of science and start studying the history of tribes, because that's what you're going to be. You're going to be the elder chieftain of the Cherokees." And they have no authority other than that arising from wisdom and competence and accomplishment.

What I like is that back in 1996, Drucker foresee how today's organizations would be: a network of acquaintances, contacts, alliances, joint ventures, minority participation, and very informal agreements... This is exactly like this, the 'tribe' concept is very relevant.
