The day my perfect simulation will be the same as all of you, then we will know we have reach "perfect".
As long as some aspect are favored over other, just because we are not all after simulating the same thing, perfection cannot be reached.
We are so far away from perfection today, even though we have made progress, that talking of perfection is irrelevant.
We don't even know what it looks like, let alone drawing the map to get there.
How about discussing what the next step should be to improve from where we are, keeping in mind most of us are in a different place right now, so even next step is almost impossible to set.
If I was to take all the parts I prefer in every SIM, to create that so called "perfect" SIM, which would be no more than the sum of the best parts available today, so, really far from "perfect" still.
Who is to say that my combination would be identical to anyone else.
It does not need to be perfect to be enjoyable, since our imperfect imagination can fill the blanks, as long as we allow our imperfect brain to play along.
