Everything I need to know I learned from science fiction

I'm reminded today of a quote from Green Mars:

She could have kissed him. Instead she nodded, not trusting herself to speak, and went to the doorway to the living room. Jackie was still in the midst of her exhortation, and it gave Maya the greatest of pleasure to interrupt her: "The demonstration's off."

"What do you mean?" Jackie said, startled and annoyed. "Why?"

"Because we're having a revolution instead."
