I'm new to science-fiction and I'm intrigued by the consequences of "Plan B". This explains the "how". My question pertains to the "why".
I don't remember what Edmund's planet would have been like but assuming Brand was able to establish a human colony on it, what might life there have been like?
I'm especially curious about the relation of the humans to the technology that got them there. Would they be able to make (sustained) use of it and attain the knowledge to reproduce it given they have access to the materials needed within their surroundings?
The underlying question would be thus: Why establish a human colony on another planet just for people to be subsistence farmers (as an example) without the means to evolve technology (and thus society) because the planetary resources won't allow it.
