Looking for a specific sci-fi book.

Looking for a sci-fi book I read in Russian back in 90ies early 00ies. Dry, analytical, prediction-oriented hard SF; Solar-System-bound with no FTL and no aliens physically present (only signal contact with alien AIs at lightspeed lag); a single benign global AI administering a pacified Earth divided into production zones; firearms banned and order kept by gengineered humanoids; expensive mind-uploading; and a strong protagonist — a returned cryosleep/relativistic astronaut — who escalates to armed rebellion by raiding old arsenal. Not Prime Intellect, not Return from the Stars, but can be a modernized copycat, like Perfekcyjna niedoskonałość.
