Exam changes: pandering to a UK who can't believe its children are getting smarter, that things could get better.
SF shouldn't be a genre. It's a moral imperative. A way of looking. To look to the future, not the past.
But these days, SF is a genre, and often deals with old visions, with what the future was.
SF seems to have given up on the future at the same point the mainstream did.
These things are connected in the UK: a country that can imagine a better future for its children would have real SF.
