I agree but I found people bounce with big intros, so it's a bad attempt at "show don't tell."
The cells were written by AI, but the metadata data that generated the cell is mixed in (thats the {...} && bit).
So now the full chat context can be derived from the notebook. Because the notebook is editable, you can fully edit the chat context in an ergonomic way. Both the prompt, the AI code output. So when the AI makes a mistake (it often does), you can correct it. Your ability to detect mistakes is accelerated by the fact it's a computation based conversation. Because the chat context is derived from the editable state, your corrections are internalised into the chat conversation. It continues as if it answered that for real.
So in the notebook you see that the AI is rapidly become an Observable notebook expert, because I have manually coarse corrected its chain-of-thought. An out-of-the box chatGPT session cannot do what is in that notebook. My expertise have been transferred. Once it knows how to solve something in the chat context, its very easy for it to repeat the pattern for new situations. Having it as a standalone forkable self-enclosed notebook artifact is useful. The existing notebook infra allows you to copy and paste cells across notebook too. So I am thinking we can curate stand alone skill memes. The examples are all over the shop just to see what kinda of things I could get it to solve, I imagine a real use would concentrate on upskilling just enough to solve a specific class of problem.
