This is a fair point, that he is discussing abstractions. I almost wrote "I wish people would read moral philosophers on moral philosophy, not tech founders."

This is a fair point, that he is discussing abstractions. I almost wrote "I wish people would read moral philosophers on moral philosophy, not tech founders." He does give some examples, and they seem to fit in two categories: things done by tyrants, and other people thinking you should expand one's moral categories. I think it's clear that the ones that bother him, in his actual life, are the latter.
