So you make an AGI, what gives it the power to do any damage? We have loads of biological intelligences, even pretty damn clever ones like Ted Kaczynski (the Unabomber)

They rarely got significant power. Those that did were super charismatic. Do you expect charisma to be easily accessible to an AGI?

The usually proposed path to paperclip maximiser is that the AGI is put in charge of a factory that can make nano machines and follows orders strictly. We don’t have such factories.

I can’t imagine anyone handing over nukes to AGI as human leaders like being in charge of them

What makes the machine brain so much more effective than Ted Kaczynski?
