pompe's "Welcome to the Future" series (

In the place of these myths he describes another set of possibilities, certainly not a set that's inevitable but at least one that's plausible.
Right now, I'm reading a book kindly lent to me by
thebitterguy that is an example of how not to write science fiction. (Thanks for the loan. I think.) All genre fictions have their conventions, I know, and sometimes these conventions are silly, but do science fiction's conventions have to be so silly? I would like the genre to continue well into the 21st century since I think that it has a lot to offer, including some good writers. The problem, as always, is with the dross and dross' inevitable conservatism. We need more radicals.
