“Predictions are just good guesses or stories for the gullible.”

“You can call it innocence, or you can call it gullibility, but Celia made the most common mistake of the good-hearted: she assumed that everyone else was just like her.”

“How gullible are you? Is your gullibility located in some "gullibility center" in your brain? Could a neurosurgeon reach in and perform some delicate operation to lower your gullibility, otherwise leaving you alone? If you believe this, you are pretty gullible, and should perhaps consider such an operation.”

“Somewhere, there, is an analogy, in a small way, if you have the patience for it. But I guess it isn't a very good anecdote. I'm better at animal stories.”

“Your guess [about the future of technology] is as good as mine. The only thing I'm sure of is (a) most of the predictions I hear are almost certainly wrong, and (b) the things that will turn out to be important will come as a surprise, even though in hindsight they'll seem perfectly obvious.”

“Gullibility kills.”
