No, you did not make the pizza, but you have the wherewithal to order it, to think of what you wanted. You don’t get to claim you made the pizza, but you made the order for your pizza dinner.

And honestly, if you have any experience at all working with AIs, then you should know very well that it is not anything like ordering a pizza.

I can guarantee you the author did work on it, plan it, rethought parts of it, specced it out, tested it, and worked a lot to make it come to life. So no, you wouldn’t have made the pizza because all you had to do was order it, but you cannot just say “write a GUI for the ZX Spectrum” and wait at your table for it to come toasty out of the oven.

Bad analogy. Bad way of thinking. Bad behaviour. All on you.
