Apparently there is going to be a special edition of New Scientist coming out on Saturday, about the future of science fiction. I'm going to buy this, read it, and tell you what I think.
I found out via Cheryl Morgan, who suspects "the main result of this will be a whole lot of people who don’t know much about SF (or sci-fi) pontificating learnedly on the subject and earning themselves spots in Dave Langford’s 'as others see us' collection."
We'll see. I'm interested enough to take a look.
