In the 20th century, we had a century where at the beginning of the century, most of the world was agricultural and industry was very primitive. At the end of that century, we had men in orbit, we had been to the moon, we had people with cell phones and colour televisions and the Internet and amazing medical technology of all kinds.

Doesn't anybody ever want to talk about anything else besides 'Star Trek?' There were 79 episodes of the series; there were 55 different writers. I was only one of them.

My approach to 'Star Trek' was, 'I know science fiction, and I know screen writing.' That was very arrogant of me, but you really need to be a little bit arrogant to think that what you have to say is good enough to justify the expense of hundreds of thousands - now millions of dollars - to make an episode of the TV show.

I think I exist, therefore I exist. I think.

When I was a kid, my favorite movies were the George Pal version of 'War Of The Worlds,' 'Them,' and 'Invasion of the Body Snatchers.' Those movies were scary! They haunted my nightmares for years, so when I started writing, I wanted to write a story that was just as big and just as scary.

Theres two tiers of science fiction: the McDonalds sci-fi like Star Trek, where they have an adventure and solve it before the last commercial, and there are books that once youve read, you never look at the world the same way again.
