The difference between the input to the carpenter and the output of the carpenter is significantly greater than the input from you to the LLM, and the output of LLM. Majority of the alterations to the wood by the carpenter produced the chair. The words you typed into an LLM are less than 0.000000001% of the total inputs that it took to create its output (because training data counts, and it’s a lot bigger than anything you may have typed)
