>Sometimes when I find someone to look up to and admire, I later find out there is potentially some dark reality to them

I too feel exactly what you are saying. I also think that a lot of good role models are simply often among less visible people, sometimes less ambitious. I am not assuming any hard correlation between the two, though. And we also need to accept that we are all only humans, not infallible. Values are more important than singular acts (within reasonable acceptance limits of course).

Anyway. I strongly recommend reading what Bill Gates has to say about AI. I can be wrong, but based on your comment it seems to me that you may find it interesting.
