Agree 100% with this. It gives the illusion of understanding, like when a precocious 6 year old learns the word "precocious" and feels smart because they have can say it. Or any movie with tech or science with <technical speak>.

While I can share the sentiment, my small experience teaching (and studying the same area for over a decade) suggests that giving students a trivial formula to play with "as is" helps motivate its future usage well. It is difficult to teach everything important about X in one go, knowledge is accumulated in layers.
