Knowing Yourself: The True in the False (1996)
“Let an ultraintelligent machine be defined as a machine that can far surpass all the intellectual activities of any man however clever. Since the design of machines is one of these intellectual activities, an ultraintelligent machine could design even better machines; there would then unquestionably be an "intelligence explosion", and the intelligence of man would be left far behind. Thus the first ultraintelligent machine is the last invention that man need ever make.”

Context: A man’ s at odds to know his mind cause his mind is aught he has to know it with. He can know his heart, but he dont want to. Rightly so. Best not to look in there. It aint the heart of a creature that is bound in the way that God has set for it. You can find meanness in the least of creatures, but when God made man the devil was at his elbow. A creature that can do anything. Make a machine. And a machine to make the machine. And evil that can run itself a thousand years, no need to tend it.

“A man needs truth like a machine needs oil.”
Often attributed to Kerouac's novel Big Sur, the quote cannot be found in that book, nor in any of Kerouac's other published works. It is, in fact, a quote by the Kerouac character in the movie of Big Sur (2013) and therefore composed by the screenplay writer Michael Polish, rather than by Jack Kerouac.
