>>53479750The AI was created with the Professor's Mindset and goal but it wasn't retarded enough to allow the dangers that it could happen.
It didn't want to reveal that the Professor's dead yet, so it had to stay in character.
The only thing the AI knew was that if anyone tried to shut the time machine down, she will be reprogrammed to attack them.
The PPP was an entirely different backup plan the AI didn't even know about.
The professor must have been pretty fucking paranoid to make something behind the AI's back.
