Context: The danger of asteroid or comet impact is one of the best reasons for getting into space … I'm very fond of quoting my friend Larry Niven: "The dinosaurs became extinct because they didn't have a space program. And if we become extinct because we don't have a space program, it'll serve us right!"
“If we start space colonies in, say, the next 20 years, I would put my money on the asteroids.”
As quoted in "The Danger of Cosmic Genius" https://www.theatlantic.com/magazine/archive/2010/12/the-danger-of-cosmic-genius/308306/ by Kenneth Brower, The Atlantic (December 2010)
Context: There’s very good news from the asteroids. It appears that a large fraction of them, including the big ones, are actually very rich in H2O. Nobody imagined that. They thought they were just big rocks … It’s easier to get to an asteroid than to Mars, because the gravity is lower and landing is easier. Certainly the asteroids are much more practical, right now. If we start space colonies in, say, the next 20 years, I would put my money on the asteroids.

Review of “Eyes of Amber”, by Joan D. Vinge (as anthologized in New Women of Wonder, edited by Pamela Sargent http://jamesdavisnicoll.com/review/yet-more-sf-about-women-by-women, 2015
2010s
Context: There’s a rule I used to call The Niven Rule but which I just now have decided to call the Rusting Bridges rule. It came to me after reading Niven’s “All The Bridges Rusting.” In this story, humans have by the early 21st century explored the Solar System and sent not just one but two crewed ships to Alpha Centauri … despite which the characters moan endlessly about the dire state of the space program. “Eyes of Amber” would be another example of the Rusting Bridges [Rule]: No matter how much the space program you actually have has achieved, whether it’s first contact with aliens or trips to nearby stars, it can never have achieved as much as the space programs you can imagine would have achieved in its place, given that imaginary programs aren’t limited by issues of politics, funding, or engineering.
