Harping on rimworld, One of the most moddable games ever made, for the creator not understanding the depths of human sexuality is a little obtuse to say the least.
There are a lot of things that people won't understand and there are so many mods to resolve this it seems silly to expect the creator to "get it".
I've been around gay and trans people my entire life but I still don't think that I fully understand human sexuality or our cultural relationships with gender norms.
Undoubtedly if I were to architect something like Rimworld I would get it wrong but I hope I would have the foresight to leave an amendment process so that it could be modded into fitting with people's understanding in the future.
Stuff only burns for so long. We might learn more about the geometry of space and that there is more out there at greater distances where maybe even other Big bangs are possible but there is a certain maximum amount of time that a star can exist.
Over the time scales of the life of a proton the maximum variability in the amount of time a star can burn is a rounding error against the scale of numbers needed to express the amount of time it takes for hawking radiation to reduce black holes to ultra long wavelengths of infrared radiation.
