No, not all humanity. Yes, lying has always existed, but simple lies are not how we got to the post-truth era. I am blaming post-truth era here on USA’s right wing. The sheer number of fabrications that lead to unjust action is astounding. It’s basically the whole platform and has millions of Americans engaged in outright harm to each other based on those lies. They take advantage of many Americans inability (or unwillingness) to see through the deceit. AI will make that worse, but these guys have sometimes taken over the country with it.
