I assume simpler thing is more probable. Additionaly - if you can design top-down and bottom-up at the same time - it means you already know what will happen.

I assume simpler thing is more probable. Additionaly - if you can design top-down and bottom-up at the same time - it means you already know what will happen. Why even do the simulation in that case? So, if we're living in a simulation - no reason to bring Gods and ultimate whatevers into this - much more probably we're just their equivalent of the Conway's game of life: https://bitstorm.org/gameoflife/ https://bitstorm.org/gameoflife/
