I don't know how accurate that is, but again it makes you wonder about the usefulness of the distinction between reality and simulation.
It's accurate in the same sense that a nuclear blast is a chance to re-landscape the garden and about as useful. It's a perfect example of Viv's Law. He is simply using a poor understanding of quantum state superpostion and wave function collapse to arrive at this idea of reality being "filled in". Many an armchair phsysicists attempting deep thoughts on reality have fallen into this trap.
