The activities and function proposed tend to be realistic or, at least, capable of construction in some way. Nanotechnology is mentioned, and used, fairly often, but isn't explained or reviewed in any depth. Di Filippo is fairly reserved in this regard, although the concept does turn out to be the most powerful one in the book. Artificial intelligence turns up frequently, but is not a strong point. If Hans Moravec's forecast is correct then Di Filippo is a little conservative, but not by much.
Virtue tends to be rewarded, and bad manners punished.
Humour is fairly broad, with a lot of heavy handed and unsubtle irony. The attempt to build a future slang can be difficult to read. It would fit with the general tone. Overall, however, the meaning of the narrative is easy enough to follow, even if the origin of some terms is not clear. This author is creative and imaginative, and, with a little maturing, could be very interesting indeed.
