This was an interesting read. I enjoyed the Tiberian sections of the story quite a lot as it's a bit of a reverse first contact, where we see from their point of view what happens when they reach Earth and find Stone Age humans. The science and engineering concepts were interesting and always a hallmark of hard sci-fi stories. I found the cast too large for the narrower scope of the story (pretty much everyone is given a name, description, job, etc even if they never get any lines of dialogue) and the plot at times slowed down, but it was otherwise an enjoyable story. It makes me wish humanity was more united in its pursuit of knowledge and of a better tomorrow.
