Humans are tough and versatile
"Inefficient little creatures once they get past their planet. Too many
things that have to be maintained and the chances for system failures
are high."
I don’t know about that. Think about this;
Humans have stood on the surface of the moon with just a spacesuit on. Really think about that. They were not in some 3 foot thick shelled enclosure- they stood on the surface in a fabric suit.
Humans are pretty tough and versatile creature. We are good at finding a way to do things when we want something bad enough.
