I&#x27;m starting to think about this along the &quot;zero-worlds interpretation&quot; - i.e. there is only one world, but it&#x27;s not based on discrete particles with states, but on probability distributions. We <i>perceive</i> the world as if it was already mostly simple, but it&#x27;s because we too are entangled with stuff. There are no many worlds of particles, because particles are not the building blocks of a world. If you look at it from the hypothetical computer simulating us, it&#x27;s kind of like storing the set of all natural numbers - you can store slices of it in lists (and then quantum entanglement under MWI works by figuring out in which list you are) vs. storing a generator function.<p>I admit I&#x27;m still in the process of learning and figuring this stuff out.
