That would be a straight-up SF story (yes, Mr Birmingham, I do 'em with or without elves and dragons) of about four thousand words or so.
Um. It's not a very nice story, you understand. There's some naughty words in it, and some very bleak thinking. But I like the central premise, and the choice that the protagonist has to make by the end, and the implications/questions it leaves. So... check it out, find out for yourself, see what you think.
