Don't get me wrong, there's some Lib shit in it too, particularly with it's representation of the conflict between Iran and Israel, but even with that I was surprised the Iranian character was presented more sympathetically than the Israeli one, also there's a kinda sympathetic Chinese communist character.
Honestly it has a lot of flaws, both narrative wise, idealistically and technical but I still liked it a lot and had an ending that, without spoiling too much, is just straight up Russian Cosmism, so much so I'm curious of the original author of the short stories is familiar with the concept.

It's a sort of mix of new-age thought and scifi transhumanism that was popular in the USSR for a time. Part of their ideology was that eventually all humans throughout history (or really all life forms) could be resurrected and saved from death and all of life could live in a super advanced communist utopia. I'm not an expert on it though, this is just the jist of it I've collected.
