Here's a Wheeler quote from the link: 'Actually, quantum phenomena are neither waves nor particles but are intrinsically undefined until the moment they are measured. In a sense, the British philosopher Bishop Berkeley was right when he asserted two centuries ago "to be is to be perceived."'
Could this be used as an argument that we are inside the simulation of the universe? I mean if I were to design a game, I might leave the state undefined until it's necessary for it to be known (by some consciousness perhaps).
The state is not really 'undefined'. Rather there is a well defined wavefunction (that is governed by precise evolution rules) that 'collapses' to a single point when a position measurement is taken. That's the Copenhagen interpretation at least :)
Yet there is something "undefined" about the phenomenon we're seeing. In the context of the quote, what is undefined is whether the the quantum phenomena is a wave or a particle. I found a name for the concept I was describing: https://en.wikipedia.org/wiki/Digital_physics
