“If theft is advantageous to everyone who succeeds at it, and adultery is a good strategy, at least for males, for increasing presence in the gene pool, why do we feel they are wrong? Shouldn't the only morality that evolution produces be the kind Bill Clinton had - being sorry you got caught?”

“When we have machines that are as intelligent - and then twice as intelligent - as we are, there is no reason why that relationship cannot be synergistic rather than antagonistic.”

“Regrettably, with '2001' having a title that had a year in it, science fiction essentially set itself up in the public's imagination as saying, 'Here's what you get if you wait to that year.' Well, we all waited till that year, and we didn't get anything at all like that.”

“You can't be a 21st-century science fiction writer writing about Mars without doing tips of the hat to Edgar Rice Burroughs, to Ray Bradbury, to H.G. Wells, to the guys who first put it in the public imagination that Mars was an exciting place.”

“All the things that made us basically nasty, rapacious, competitive as a species are not necessarily hard-coded into whatever passes for the DNA of artificial intelligence.”

“George Orwell's science-fiction classic 'Nineteen Eighty-Four' wasn't a failure because the future it predicted failed to come to pass. Rather, it was a resounding success because it helped us prevent that future.”

“I am part of a minority that is deeply misunderstood. People have very confused ideas about us. Many are frightened of us. I've even heard it said that many people wouldn't want their daughters or sons to marry one of us, and I know of people who have been denied jobs or promotions because they share this trait with me. But being what I am does not make me bad; being what I am does not make me dangerous; being what I am does not mean I don't love, or hurt, or have a sense of humor. My name is Malclom Decter, and I'm here today to tell the whole world what I am. ... I am an atheist.”

“I get tired of hearing some science-fiction fans saying that characterization isn't important in SF. In point of fact, I think it's probably more important in SF than in mainstream fiction. After all, if the author can't characterize humans well, he or she probably can't characterize aliens well either.”

“Gone. and it was completely. Everyone I'd every known, every place I'd ever been. My Mother. My father. Rebecca. Out of site. Out of mind.”

“Naturally, one does not normally discuss plans to commit murder with the intended victim.”
