This is all good stuff. I've seen it dozens of times in my corporate experience. A rookie gets promoted too far and too fast. They inevitably self-destruct somehow. Their ego gives them a sense of infallibility and invincibility. They will always go a bridge too far, and nosedive. I've seen it over and over and over.
Whatever happened to that mean-spirited, arrogant, anti-gun high school kid? He got himself disappeared. He was another young kid who did not understand humility and respect, for anything or anyone. And now he is gone.
There is a reason that the Bible and countless self-help success books push and emphasize 'humility' above all other behaviors. This is because arrogance and hubris are dangerous and fleeting attributes. To be respected, one must show respect to others, no matter who or what you are. This is a lesson lost on youth. And AOC is as young as it gets in terms of Congress.
