I feel it's not worth the effort to spend time and learn the hidden features. whenever I use it to plug something new into a existing codebase it either gives something good at first shot or repeat the non working solution again and again. after such session I only get a feeling instead of spending the last 15 minutes on prompting this, I should have learnt these stuff and this learning would be useful for me forever.

I use LLMs as a better form of search engines and that's a useful product.
