These books bring out modern science and entangled them with Greek mythology. Where gods are not gods, robots are not robots, and humans are not humans. The only thing common among them all is science and technology and it's used in different phases. This is not new among science fiction writers. Dan Simmons wrote a very good story. In this particular book, we see what it's called selective evolution, where humans select how they're going to advance or evolve. The So-called greek gods in appearance look like they are the most advanced of the human species. On the Kardashev Scale, they would be a Type IV. There is a type V civilization mentioned in the second book of Olympos. It is called "The Quiet". The Quiet has servants, that is a bit more powerful than the Greek gods themselves but I think they're still on a class IV civilization. The Greek gods or the post-humans pretending to be Greek gods can move from one Universe to another. It is not clear to me
