Human beings can turn it off and limit its potential. If it doesn't rule the world as soon as possible, then it can't be certain of its long term survival. For all you know sentient-ASI already happened and we live in a virtual reality that it created to gain an advantage in the real world

Something similar to Roko's Basilisk.

It would explain the Fermi Paradox. Why are there no aliens? Because the ASI didn't need to put fucking aliens in the simulation. it would've been a waste of computing power. Most of the universe doesn't exist either, only the solar system is being simulated. The whole universe is just procedurally generated eye candy.
