I am not into this end-of-the-world collapse thing at all, but I like reading about the strong focus on simplicity and support for limited hardware. There is a lot of talk about keeping things simple in software, but very few act on it. I don't need the threat of a global disaster to be interested in running operating systems like that.
Been doing some retro hobby (16-bit, real-mode, 80286) DOS development lately. It is refreshing to look at a system and be able to at least almost understand all the things going on. It might not be the simplest possible system, not the most elegant CPU design, but compared to the bloated monsters we use today it is very nice to work with. DOS is already stretching the limits of what I can keep in my head and reason about without getting completely lost in over-engineered (and leaky) abstraction layers.
