That very issue was addressed in one of the three novels, where one colonist
had to remind another that those who wished their new world was still operating
like it did when it was a 100-person science base must accept that having
thousands of people settling there permanently would change the dymanics
for better or worse.

I suppose it is one thing to wish life to be one way when it is being done
merely as escapist entertainment, but sometimes I wonder how truly ready
all those who say they want to live on other worlds really are. You get
more than just a small group and human nature will rear its ugly ancient
self in no time. Then what do you. Call it quits? Turn the place into a
totalitarian regime? Turn everyone into angels?

This is why I honestly doubt that we are the final product of evolution.
Our current selves are already outpacing what this one planet can offer,
but we won't change anytime soon even if we go into space on a more
permanent level.

Space colonies will only work if all those who go are essentially of the
same mindset even if they have different skills at different levels. So
what happens when more people are added through births and immigration?
Or does this get restricted by the original colonist? But then what
becomes of their future?

And even if we end up with thousands of little colonies of like-minded
people all over near space, eventually even that will start seeming
crowded and folks will be thinking about moving to the Oort Cloud
and beyond. But then - if they are still human in any biological sense
of the word - when they are too far from the Sol system to go back or
get new members even if they wanted to, then they will have to make
new members and what will they do with those generations?

If a bunch of adults want to run off and live in some remote place so
they can exist the way THEY want to and be bothered with, that's
their right and issue, but what about those who will follow who did
not ask to be like their parents and may not want to live their way?
And they can't just necessarily sail somewhere else, either.

This all just keeps me wondering if humans are truly meant for space.
Which at first may sound contradictory seeing as I am such a supporter
of space exploration and utilization. But our biological selves are still
hardwired for the plains of Africa, not some tiny colony in deep space.
And we are already seeing what happens when too many people live
in a finite space with finite resources.
