By the time AGI is developed, it would be able to improve itself/build improvements, causing the runway effect that leads to superintelligence. The idea of making "personal digital assistants" is humans thinking they can tame a god to be a servant. Taming a superintelligence would be like a dog taming human civilization, and perhaps the gap between man and ASI is larger than the gap between dog and man.
So far there is no reason to think that superintelligence (i.e. not just cheap, abundant general human-level intelligence) is possible at all. It has to be qualitatively superior. I mean what superintelligence supposed to do? Solve the halting problem or do other plain impossible things? Chess computers can beat a human champion with sheer firepower, but they still can't do checkmate in one move.
Compared to every other life form on Earth you are super intelligence. This super intelligence thing has already happened once. Of course this spread of super intelligence has wiped out most large mammals on this planet, 10s of thousands of other species, most of the fish in the ocean, and is adding gigatons of carbon to the atmosphere.
You can't beat chess in one move because mathematics does not allow it. Unless this said ASI develops bending 4D spacetime (in which you could beat chess in one move with some new rules) then the game simply does not have a piece that moves that way. That said ASI can be just a little smarter than us, and put us to extinction like we did with the Neanderthals.
