does this imply we are all simulated? if nothing is conscious and observing an object, just like in a computer game to save cpu clock cycles, simply don't render the object, you only render what you look at and nothing else...
if you're looking in front of you and nobody else is in the room as you, behind you doesn't get visually rendered and if there's no observer there's no sound no nothing, it only exists because you observe and will it into existence, or at least this is what the observer effect implies...
what says you?
