I find it hilarious that people think they are informed on all the topics they consider themselves informed on. There is simply way too much information out there to be well-informed on all of it.
I can't be an infectious disease expert. I can't even be reasonably informed on all the stuff that goes on surrounding it. I need a sieve. I need filters. I need vetters. I need vouching. I need those who are informed on a topic to do all the legwork and present the results. And that's not you or other randos on the internet.
And that's what we've actually lost. We've lost all the filters and firewalls that stopped the majority of misinformation. With everyone having a global megaphone to broadcast their every thought, it's become harder to discern between those who are informed on a topic and those who aren't.
The world's signal to noise ratio is weighted too heavily towards noise.
