I am looking for a short story about a father and son (the mother is out of the picture) who are of a religion that doesn't believe in body modification or enhancement.
It is set in the future when that is a common practice, and they are on a spaceship (or some such place) where the only work available to the boy is by accepting the body modifications in order to work on something in an extreme environment. He does and the complications follow.
The story also has some super all-answers computer/instructor, like the Internet with a personality.
