Norman, Bruno and List:

In #2 I vote for Bruno: 'Nescio no est argumentum',
the fact that we "don't know about..." is not
applicable as an argument.
In the question of a 'simulation', however, I find a
more intrinsic point: (IN MY VOCABULARY) information
means "difference acknowledged". So whatever we (can?)
get to knowing is some difference. What means that a
'perfect simulation' (=the thing itself?) does not
show up as 'another thing' in our mind. (Matching
Bruno's view maybe in other words - not far from
Norman's either).

(This is my argument (untold and not submitted as an
argument) - against the infinite 'imitations' of 'our
universe' in certain Multiverse visions. IMO the
universes are different, infinitely in any qualia,
otherwise it makes no sense (to me).)
