Someone with more knowhow in a context will be like a wizard.

How does it work?

They have loaded up their System 1 with more relevant experience.

But also they're able to "chunk" memories at a higher level.

Grandmasters of chess can look at any chess game and remember it in a second or two.

But if you show them a random board (i.e. not one generated by a legal game) they are no better than a novice at recalling the positions of pieces.

The grandmaster is chunking the knowledge of the board at a much higher layer of abstraction.

People who are able to work at higher layers of abstraction will be more effective with LLMs.
