I agree with you. There would be no X without Y person. Undeniably. The scope of the project matters seems clear though. I think it should be clear and obvious what one means when they say "I made this" recipe from scratch. Even then, there's "did you invent this recipe!?" or do you mean you "prepared it in your kitchen?." That scale and scope is very different from what it means to make a film. And it's where I agree, there's substance to a Hitchcock film being made by Hitchcock. It doesn't mean he literally wrote, acted, set/wardrobe-created, and filmed the movie! But we're losing the plot here to give a similar substance to "I made this app" and allow it to mean one-shotting Fable to clone the latest "you don't prompt AI, you build your empire with a team of Agents" orchestrator.
