In other words, I tend to think that people who make philanthropy their career and who have accumulated various impressive markers of their potential to improve the world are likely to continue to accumulate impressive markers, but are less likely to improve the world than people who have already actually improved the world.

And of the three core staff members of SI I have gotten to know, 2 (Eliezer and another one who probably does not want to be named) have already improved the world in non-negligible ways and the third spends less time accumulating credentials and impressiveness markers than almost anyone I know.
