It's not polite to say, but I have noticed a direct correlation between the skill level/knowledge of people I know and the quality of results they get from LLMs.
Heck even in my own usage I get far better results when using them in domains I know vs domains I don't.
This take is so cold I can use it to reduce my house's cooling bill.
Why? If I have more skill and knowledge in a specific domain I can better breakdown problems, prompt an LLM better, and actually verify correctness.
Yes, literally nobody in the entire world disagrees with that.
Hence why it's a cold take. I'm sure you know what a cold take is.
