The director of the Institute for Countering Artificial Intelligence Threats is killed by his own son. At least this is indicated by video recordings, witnesses, and the culprit himself does not deny that his finger pulled the trigger. Yes, the hand is bionic, but it is impossible to hack it, because after a nuclear disaster provoked by AI, there are no chips in the prostheses, they cannot be hacked. Nevertheless, Aj intends, if not to prove his innocence, then at least to find out who the real killer is.
