If you go to a coffee shop and ask extra ice, less sugar, more vanilla - did you make the coffee or the barista make the coffe and you just gave some requests to him. Using an LLM is far more similar to ordering coffee from a barista than it is to actually making the coffee. Of course the barista didn’t make the seeds, the milk etc. This is not an exact lawyerly statement.
But intuitively, you didn’t make anything when Claude Code writes all your code.
