I'd argue that the systemic critiques of Don't Look Up include folks simply listening to who they want to without regard to facts, the snowball effect that social media has when it comes to misinformation, and the gap of perception and reality are exploited for someone's gain (even if it's a detriment to everyone).

The premise of idiocracy is literally "what if everyone in there future were idiots and there's one average person from the past added to the mix?" and how they got there is the opposite of eugenics.
