#one might even say that the hyper space capitalist humans had been... atomised...

Could Sirenians ever integrate back into human society? And would they?

I mean sure I don't see why they wouldn't be able to if the will was there (bearing in mind they are not a monolith) buuuut there's no human society to integrate back into. Even if humanity wasn't 99.99% extinct as fuck, before its demise there was nothing that could be described as human society, not even on Earth. there were only corporate bodies and scattered colonies, most of which had had nothing to do with one another for hundreds of years. Ceti, the planet which was used as Atom corporation's home base, was privately owned by the company, and that was the general trend of basically everything before the Siren mission. Things like nations, or planet-nations even (once the population spread over more than Earth), had not existed for a long time.
