> I think I am the only one who think humans will never manage to build something that complex. The universe is impossibly large, but it's not fundamentally complex. All complexity is emergent, not built in. The universe may very well run on a few very simple rules of data transformation, like a collection of cellular automata. I don't think any physicist would argue in favor of the universe's complexity in connection with the simulation idea. In my opinion a better implausibility argument could instead be constructed from the enormous size and the apparent wastefulness of calculating every single simulation tick (which may well be equal to Planck time).
