I'm pretty sure nobody ever implied (or could support in any way) that a certain archaic invention definitely came from males. As a non-native English speaker I always took "man" to be a synonym for "human". As in "mankind". Would the objection made by the professor above imply the terms should be changed to something like "personkind"?
