Not necessarily, because often "those who go" don't have any choice. For
example, English who colonized Australia were convicts expelled from England.
Also, many who came to America were "losers" who could not cope with the
situation in Europe, or (as another example, the Irish) emigrated because of
disaster in their homeland. So, it could be that the best and the brightest
are the ones with the least reason to emigrate. Christopher Columbus was brave
to cross uncharted seas, but was he more confident in himself than Galileo who
never left home?

What about the Africans who travelled great distances from central Africa as
slaves?

I see where you're going with this, but you've failed to reckon with the
negative aspects of migration, such that selection pressure may operate to
drive out the unfit (or less fit) members of a population, leaving the best
back home where they have secured good reproductive options for themselves.

Yes, and it works both ways: Those who hate the successful and non-traditional
may be the very ones to travel to distant lands to set up communes to practice
primitivism. As P. J. O'Rourke has said, "America was founded by religious
fanatics with guns." The Pilgrims were not avante garde intellectuals, after
all.

Quite the opposite: The poorest are driven to the "adventurous" task of
desperately seeking sustenance by traveling to distant lands. Of course this
"adventure" may itself constitute a selection process whereby the fittest of
the travelers are the ones who survive and reproduce, as in the Westward
migration accompanying the slogan "Go West, young man."

Extropianism can indeed represent a migration to more highly evolved systems
of organization. However, this need not be connected to geographic or spatial
migration as much as it is connected to migration toward more complex adaptive
ecology within the space already occupied.
