From an utilitarian point of view, AI only have to create less problems that humans.
When I see physicians like Lynn Webster prescribing insane doses of Oxycontin for any injury, ignoring the warnings of the people dealing with the disastrous results and finally making up excuses for the death of his patients, I am pretty sure a lot of families would have preferred to take their chance with IA.
But of course, a fully utilitarian society would probably be a nightmare.
