> Perhaps naively, I'd have thought someone intelligent enough to develop a technology like this would also be intelligent enough to understand the complex ethical issues it raises. It seems, unfortunately, that there is no such correlation.

Correct. There is a tendency to think that because a person is exceptionally intelligent or skilled in one area, they must also be intelligent in other areas. It's simply not the case. An expert is authoritative in the areas of their expertise, but outside of those, their opinions are no more likely to be correct than anyone else's.

This error is often leveraged in persuasion campaigns -- thinking that, for instance, a brilliant physicist's opinions on social policies are more likely to be accurate than any random person on the street.
