But this battle is not just about the machines, but about Narus, and it’s people who were going to pose a great threat to John as he would grow up being hated by humanity because he was good and had leadership qualities. See, even he did not know that the birth of AI was also his subconscious command which would prove to be able to wipe out the current threat of a majority of the people and leadership of Narus. It would only be far late in time that John would realize the importance of machines taking over something that Narus was always against as it saw bio-engineered citizens as its weapon X. John with the help of Skynet later starts a war with the resistance which thought John to be abducted and compromised, but was protecting only to bring Narus back.
