Who will ask them? FAI have no idea, that a) baby eating is bad, b) it should generalize moral values past BE to all conscious beings.

Even if FAI will ask that question and it turns out that majority of population don't want to do inherently good thing (it is for them), then FAI must undergo controlled shutdown.

EDIT: To disambiguate. I am talking about FAI, which is implemented by BEs.

As we should not allow FAI to generalize morals past conscious beings, just to be sure, that it will not take CEV of all bacterium, so BEs should not allow their FAI to generalize past BEs.

As we should built in automatic off switch into our FAI, to stop it if its goals is inherently wrong, so should BEs.
