Let's say you have a computer program with 10,000 lines of code in it. How many bugs are there? OK, 100,000 lines, are there 10x as many bugs or 12x? 1M lines? Let's say you have a 10M-line computer program, there are going to be tens or hundreds of thousands of bugs in that thing.
How many bugs have we seen in reality? I don't mean "Oh, _that's_ interesting" and later we figure out general relativity - I mean bugs, the shit bluescreens, or if you look in a certain direction, things are different. How many have we found?
AFAICT, we've found _zero_. Every time we find a discrepency in the universe, later we figure out that it wasn't a discrepency, it's how the entire universe works, and our previous understanding was simply wrong. EVERY TIME. So either the bugs self-heal and become consistent universal features, or they weren't bugs in the first place.
If the universe is a self-organizing emergent property on some very fundamental operator, then I don't see how "simulated" differs from "real". We don't write software that way. We don't build hardware that way. I don't mean a little bit, I mean AT ALL, that's entirely alien to everything in software and hardware, to the point where you might as well be talking about something else entirely.
