i know nicola tesla and albert einstein have been instrumental in getting us to the point that solar powered cars are the std issue, the status quo.

but, what about a world without the advancement of technology? the siberians, american indians, etc. had bows & arrows. can we allow that?

so, just how much technology is enough? anyone know for sure?

humans without technology? is that a oxymoron?

we're meant to populate the planets around the stars, or not?
