This is a good point; I agree that it's good that we have a nuanced and realistic (as opposed to pessimistic) view of the situation. As someone else pointed out regarding the Dunning-Kruger effect, the less knowledgeable we are the worse we are at understanding our own level of knowledge. Regarding your comment, not understanding the "unforeseen or unknown problems you encounter once you are going" could be catastrophic in certain fields.
