Usually when you learn difficult skills, you can go to a trainer, take a class, read about the solutions.

Right now, you are entirely up to the random flawed information on the internet that you often can't repeat in trials, or your structured ideas on how to improve a thing.

That is difficult. It is difficult to take the information available right now, and come up with a reasonable way to improve the performance of LLMs through your ingenuity.

At some point it will be figured out, and every corporation will be following the same ideal setup, but at the moment it is a green field opportunity for the human brain to come up with novel and interesting ideas.
