There’s a lot of varying beliefs about what the future holds, especially when espoused in science fiction. The fact that anyone can look at the history of our planet and then postulate through science fiction that anything that failed in the past will work in the future because “the right people will be running things” really makes me scratch my head.
Mike really makes an observant point, one that I missed when I first read Heinlein’s Friday. It’s one that I more or less copied when I came up with the basis of Wraithkin. You should take a look.
