An SF author who reads only SF will have little new to contribute, but someone with a broader experience will bring more to the table.

When state and religion are one, religion becomes a means for the powerful to remain in power.

Some of my ideas were shot down by Lucasfilm because they stepped on territory that has been reserved for the movies. I didn't have a problem with that.

Right up till the 1980s, SF envisioned giant mainframe computers that ran everything remotely, that ingested huge amounts of information and regurgitated it in startling ways, and that behaved (or were programmed to behave) very much like human beings... Now we have 14-year-olds with more computing power on their desktops than existed in the entire world in 1960. But computers in fiction are still behaving in much the same way as they did in the Sixties. That's because in fiction [artificial intelligence] has to follow the laws of dramatic logic, just like human characters.
