I'm wondering if it could be a scenario sort of like A Canticle for Leibowitz, where humanity has, in the wake of a major disaster, decided to destroy all technology, except in this case the technology is preserved by a subset of humanity in space. The ones left behind, though, after several generations, have forgotten all about the technology, and so what Alice does looks like magic to them. Amos, on the other hand, may be from the original generation that destroyed the technology to begin with... which would explain his apparent hostility to Alice and his suggestion that things are best left forgotten.
