It's influencer culture. It's like when people watch those "software developer" youtubers and pretend it's educational. It's reality television for computer people.

Prompt engineering (to the extent that it results in the difference between applied LLM success vs failure) requires the human to truly grok what they're getting help on - the current top comment notes that the model applied more or less exactly the same diff they would have done, based on deep understanding of the exact codebase being modified - and also have some level of intuition about how LLMs work.
Someone just treating the model and context like an obscure TV remote and pressing all the buttons to see what they do, will get a result, and it might seem interesting, but will it be ontologically correct? Good question!
