I think the biggest learning from covid is that everybody can choose their own truths and facts, and the internet can provide a limitless amount of support for any theory, hypothesis and conjecture about all of them (even when they're diametrically opposed).
COVID-19 launched us so far into the post-truth world that I'm afraid there's no way back.
I don’t honestly know if we are more capable of finding the truth now or prior to modern social media and COVID. To me it seems plausible that the truth of things was always abysmally obfuscated by those in control of information distribution. But now we have become very aware of it.
The distinction seems critically important but I don’t know how to figure it out for certain.
