"You're a hacker, that means you have deep structures to worry about, too."
"Deep structures?"
"Neurolinguistic pathways in your brain. Remember the first time you learned binary code?"
"Sure."
"You were forming pathways in your brain. Deep structures. Your nerves grow new connections as you use them - the axons split and pushed their way between the dividing glial cells - your bioware self-modifies - the software becomes a part of the hardware. So now you're vulnerable - all hackers are vulnerable - to a nam-shub. We have to look out for each other."
"What's a nam-shub? Why am I vulnerable to it?"
"Just don't stare into any bitmaps..."
― Neal Stephenson, Snow Crash. (1992)
"The paraphrase of Gödel's Theorem says that for any record player, there are records which it cannot play because they will cause its indirect self-destruction."
― Douglas R. Hofstadter, Gödel, Escher, Bach: An Eternal Golden Braid. (1979)
