Every permutation of leadership has been tried at some time or another, and
in fact most are still being tried in one country or another today.
None is universally accepted yet, and I can't foresee that any will either.
It might be instructive to look not at leadership, but followership.
Few want to lead, but many want to follow. It's easier, and allows them
to get on with whatever they =do= want to do with their life.
To that end, I see multinational corps, mass marketing, and computer
programs as being the new (untried) things that people will follow,
mainly because it's easier, and (in the light of software) reduces the
options presented, especially as networked databases learn more about us
individually, and tailor their presentations to that.
We may end up following, without any leader.
