It’s a book series. It’s a semi utopia based sci-fi. The culture is an amalgam of species (including human). It’s run by “minds” hyper powerful AIs. Humanity is akin to pet dogs. A mix of pampered and useful.
Basically, humans live in a life of luxury and choice. Changing genders, or even species is very common. Immortality is mostly a logistics and boredom issue.

















The allies, in WWII had a similar choice. They decided not to kill Hitler. At that point he was making enough mistakes that his replacement would be sufficiently more competent to outweigh the benefits.
Right now, Iran is a quite limited war. Going after trump would massively escalate it. Iran doesn’t want mushroom clouds over multiple cities.
