> A technologically advanced civilisation is also likely to rebuild their organic bodies specifically to overcome these limitations... I wouldn't be so sure. It is a question of philosophy really, but there is the argument to be made that a change in form correlates with a change in function, even to the point of changing what a mind is. Suppose humans did that, changed our bodies to survive different environments rather than change environments. At some degree of modification these changed creatures would no longer be human, even in behavior, not just appearance. Where is that degree? And then, what's the point? What is our goal, to spread earth's version of life, it's biosphere? Or to spread minds and create more? Or to spread humanity? If it's the last one, it makes no sense to extensively modify our bodies, because you wouldn't be spreading humanity, just life, or just minds, at which point why not just send tardigrades or awesome computers into space?
