Not trying to be a rude but why even make this comment? Just saying something is bad and inferring people are amateurs without offering any insight yourself is just as useless as the opinions you think are uninformed
Seems like the point of the comment is a reality check against hubris. This can have value to help people who don't know what they don't know begin to understand what the things they don't know are. Possibly the most valuable kind of learning at all.
