And even then, if you look at quantum mechanics through the right lens, its apparent randomness is only an illusion of perspective. If you flip the quantum coin, then with 100% certainty, perfectly deterministically, it will come up heads in one timeline and tails in the other. It’s only because your two future selves can’t interact with each other that they can’t have an argument about what the result “really” was, so one says, “it actually came up heads, and the result was completely random,” and the other says, “it actually came up tails, and the result was completely random.”
It’s a reference.
