The whole idea that "we need to decide" presumes that there is a collective "we" that's separate and distinct from the individuals and corporations releasing this stuff into the world, and that "we" participate in a collective decision making apparatus that has any effect whatsoever on what new capabilities get invented and released into a networked world where borders, boundaries and jurisdictions are all but meaningless.
When it comes to manage the insanely complex systems that form society, I think I would choose an incorruptible (if biased) AI before a fallible human being any day.
