was thinking sim geography update maybe , but assuming that time is not an obstacle , if you can run this kind of a super comprehensive dataset it would be easier to just start over with new expected conditions than to import and update unless you were testing something very specific in real time . and would be sloppy to test in one of your prod environments and leave so many memoriesglitches intact unless that is one of the relevant conditions for testing . also makes every interaction dependent on algorithms and no more free will , just reactions . Multiverse collapse answers environmental questions and theoretically even why the entire universe keeps expanding , but should be a hella lot more divergence than differently spelled products at a micro level . different anatomy , sun , tidal pull , etc through all of recorded history will produce more changes than giving me a new fish to buy for the tank . so nothing makes too much sense yet , but maybe it will eventually .
