There are a few parts of the book, according to the translator, that are done in the manner of a Chinese folktale, which he tried to translate to a different style in English. I'm no expert, but I got the impression the sophont chapter was in this category. It has this otherworldly silliness with the multiple attempts to create a sophont going wrong in different dimensions, calculated to fit the repetitive pattern of a fairy tale.
I think the thrust, which might be hard to read in translation, is this: we can't imagine the technology a superior alien species would come up with, so it's related as a fairy tale beyond technological realism.
Anyway, I doubt it was meant to be hard sci-fi.
Which was extremely disappointing, given that it was billed as such by many, and until the aforementioned mumbo-jumbo was doing a seemingly nice job on that front.
It was such a letdown, the book starts great, and then the explanation turns out to be magical Alien proton computers? Yikes. It was so promising.
I eventually read the whole trilogy, I have very mixed feelings about it. It had some pretty cool ideas but it's hard to get past all the giant plot holes and outlandish fantasy. I guess you have to be in the mood to constantly brush off the bad parts (and boy there are many) and plunge forward.
