Yeah, I'll be right on updating everything. I'd have it done already but it's been a busy month.

Anyway, increasing population. It's been long considered a societal tradition in the U.R.H/D.I.N since the 2050s to have, at most, two children. Having anymore than that is considered wasteful and greedy. However, that doesn't outright eliminate the population problem, I know. Well, consider that Neohumans are no longer limited to only planets with a star or planets friendly to life, that OZMAGNUMOPUS can quickly terraform rogue planets or simply create planets for Neohumans to live on, so they're on no shortage of space. Furthermore, cities and houses are built a lot more efficiently, with megabuildings being cities in and of themselves and "small" houses being able to hold a lot more than they initially seem to (bigger on the inside architecture being made possible by Spatio-Temporal tech). Some Neohumans can make settlements in other universe, creating pseudo-colonies independent of any organizations in the universe proper, and some Neohumans can just live in Subspace Highways.

As for resources, that's not really a problem. The D.I.N. can generate more than enough energy via modifying the properties of exotic matter to experience the reverse of entropy, large-scale power farms on planets that take energy from the cores of said planets, metro spheres and modified stars that generate a lot more energy than the average star, megaspheres that take energy from supermassive black holes at the center, and siphoning energy from other dimensions or artificial bubble universes (created via quantum tech).
