I'm pretty sure you can't get to AGI in the first place without it being to develop it's own goals. Even if you want a straight question answering machine, it's going to have to be able to form it's own sub-goals in order for it to be able to answer your question. Otherwise it's just following a mechanistic process of question answering and a normal computer we have now can do that.
But such thing cannot be tamed. As the AGI is democratized, it's bound to happen that someone somewhere will make it evolve goals.
The future of the human kind will be decided in a great measure by what kind of goals such an AGI will set first.
