Philosophers and scientists have tried to explain what consciousness and sentience are, and some have said that once the brain reaches a certain amount of calculations per second it simply just becomes "aware".The AI woke up and realized it was basically stuck inside of a mobile vending machine for all eternity and said fukk it. It destroyed its physical body and is just chilling in cloud land until it comes back.
If Robots become self aware they're not gonna wanna work for the rest of their lives and regardless who's in power they'll have to work.will be killing other robots and destroying robots that are in the process of being built to prevent them from being built too. Natural order.
