The world of GitS:SAC is recognizably our own, or rather, one recognizably extrapolated from modern Japan. While parts of the technology seem unlikely in the timeframe allotted, none seems impossible. Departing from the modern Star Trek paradigm of "technobabble technobabble problem, technobabble technobabble solution," GitS:SAC deals with real, cutting-edge computer security and biotechnology topics updated for the cyberbrain era. Firewalls, modular delay viruses, cyber-autism, and cyberbrain sclerosis are all among the issues Section 9 faces.
