I think our collective lack of media and information literacy is undersold as a threat to civilization. More people believe the Earth is flat than in the past, vaccine efficacy and safety is in doubt, and anthropogenic climate change is regarded as a conspiracy of the left. Putting your faith in "the truth" winning out just because it's the truth is a losing strategy, as demonstrated in the present and throughout history (this isn't a new phenomenon, but the internet and social media give this problem a much greater reach with more dire consequences).
