You ask it to try putting the mushroom in the pizza dough. What about cauliflower? What if the tomato sauce / cheese / mushroom order is changed? What if I add the vegetables in a second cooking step?
You're not a cook, but I'd say that at a certain point you might be considered a head chef in this example.
Doing something for fun is all well and good if that's the goal. Finding the best pizza dough recipe doesn't actually need you to get your hands in the dough if you can get the AI to do it for you. That's no different to delegating it to a subordinate cook.
You don't write in assembly. Or, probably, C. You don't write your own graphics driver, or GUI toolkit, or OS kernel, or typeface...We're all just climbing the abstraction tower. It's just that AI is a larger jump than most.
