It’s a difficult Fourth Turning moment.
Podcasts like TWIV (this week in virology) consistently dismiss social media videos as unverifiable, which is the safest assumption to make. Could be old videos with new captions, etc etc.

On the other hand, there is widespread distrust in institutions that should be giving us the verified truth.
The trusted institutions are telling us the rustling in the bushes is just the wind, and social media says it is a tiger. I will personally act as though its a tiger until the truth comes out.
