I would say it is. The OP is right that there are many things in life that we don't know for sure, and that it can be liberating to realize that we don't have to have all the answers. However, the idea that ignorance is a virtue is simply absurd. Ignorance is the root of all kinds of problems, both personal and societal. It is only by constantly expanding our knowledge and understanding that we can hope to make progress in the world.
Yours or mine? :) I mean GPT is clever enough that anything might fall under suspicion. But the one I was referring to just didn't seem to have any truth to it and not even much internal coherence beyond contrarianism.
