I came upon an interesting passage in "Our Mathematical Universe", starting on page 194, which I think members of this list might appreciate:
"It gradually hit me that this illusion of randomness business really wasn't specific to quantum mechanics at all. Suppose that some future technology allows you to be cloned while you're sleeping, and that your two copies are placed in rooms numbered 0 and 1 (Figure 8.3). When they wake up, they'll both feel that the room number they read is completely unpredictable and random. If in the future, it becomes possible for you to upload your mind to a computer, then what I'm saying here will feel totally obvious and intuitive to you, since cloning yourself will be as easy as making a copy of your software. If you repeated the cloning experiment from Figure 8.3 many times and wrote down your room number each time, you'd in almost all cases find that the sequence of zeros and ones you'd written looked random, with zeros occurring about 50% of the time. In other words, causal physics will produce the illusion of randomness from your subjective viewpoint in any circumstance where you're being cloned. The fundamental reason that quantum mechanics appears random even though the wave function evolves deterministically is that the Schrodinger equation can evolve a wavefunction with a single you into one with clones of you in parallel universes. So how does it feel when you get cloned? It feels random! And every time something fundamentally random appears to happen to you, which couldn't have been predicted even in principle, it's a sign that you've been cloned."
