I would argue that we have a generation of young people particularly minorities who are no longer putting up with the kinds of things their parents put up with. They're much more self-confident. It's no longer acceptable to make fun of people because of race or sex. But it has always been present in American society.
We've outsourced our memories to digital devices and the result is that we no longer trust our memories. We see every small forgotten thing as evidence that they're failing us.
