Set in the future where there is at least one 3D printer in every household, population demographics show aging in every part of the world. In this future, many elites have powerful AI nanobots running inside their brains to assist them with decision making as well as being informed about the relevant current event happening in the world right now. These tiny nanobots cannot replicate by themselves and have to be 3D printed. Usually people of higher social status are often manipulative and will try underhanded method such as involuntarily feeding their workers or slaves with nanobots to eavesdrop and monitor their daily activities so as to blackmail them in due time. There has been a rumor going around for sometime regarding the rich and powerful using AI nanobot to control the corporation, and even the entire nation. So what is stopping people from creating their own similar AI nanobots assuming 3D printer and materials cost are dirt cheap?
