There is a side-effect mentioned in the novel as a negative. When these nanobots are introduced into a population the “problem” is that chemical contraception stops working. Vasectomies are healed as would other forms of surgical sterilization. Abortion also becomes much harder as the child heals faster than they can kill it. This is remarked rather off-handily in the novel and is really not part of the plot.
I need to sync my reading list with The Curt Jester's
