This is book 3 of the Remembrance of Earth's Past series.
This book worked for me. This whole series worked for me. In a way I really wasn't expecting it to work.
I enjoyed the science fiction, space opera, weird tech elements of the book. I found several aspects of the book difficult, the parts where civilization falls apart and all.
Two parts really stuck with me. The first was that Cheng Xin completely and totally doomed humankind in its entirety. The second was the portrayal of the rich of the rich of humanity's reaction as Xin flew off. The latter I have quoted somewhere in here.
As many other people have, I enjoyed the series after I was able to get into it. It wasn't what I expected, and that was part of the delight. I recommend the series to any science fiction fan.
A new technology can transform society, but when the technology is in its infancy, very few people can see its full potential. For example, when the computer was first invented, it was merely a tool for increasing efficiency, and some thought five computers would be enough for the entire world. Artificial hibernation was the same. Before it was a reality, people just thought it would provide an opportunity for patients with terminal illnesses to seek a cure in the future. If they thought further, it would appear to be useful for interstellar voyages. But as soon as it became real, if one examined it through the lens of sociology, one could see that it would completely change the face of human civilization. All this was based on a single idea: Tomorrow will be better.
