From Kurzweil Accelerating Intelligence on Patrick Tucker’s The Naked Future: “Computer scientist Stephen Wolfram, and futurist Ray Kurzweil have famously painstakingly recorded every minute detail of their lives, from their diets to the keystrokes, in order to quantify and better their lives. Now, technology has made self-quantification easier than ever, allowing the “everyman” to record and study their habits just as Wolfram and Kurzweil have done, but with less hassle… So what happens in a future that anticipates your every move? The machines may have a better handle on us than ever, but we’ll live better as a result. The naked future is upon us, and the implications for how we live and work are staggering.”
“In all fictional works, each time a man is confronted with several alternatives, he chooses one and eliminates the others; in the fiction of Ts’ui Pên, he chooses— simultaneously—all of them. He creates, in this way, diverse futures, diverse times which themselves also proliferate and fork.” The Garden of Forking Paths by Jorge Luis Borges.
From the Stanford Encyclopedia: Branching time semantics: “As an explicit (or formalised) idea, branching time was first suggested to Prior in a letter from Saul Kripke in September 1958. This letter contains an initial version of the idea and a system of branching time, although it was not worked out in details. “
