You're wrong because you are making the wrong comparison.
In this analogy, The guy down the street didn't cook his own steak. He told someone else to cook the steak. And then claimed that he himself cooked it. Telling himself, "wow, I'm a great chef!". When In fact, he did not cook the steak.
Your greatness as a chef isn't measured by how well you manage restaurant kitchens. That would be a great manager. Your greatness as a chef is measured by actually cooking yourself. Claiming other chef's work as your own would be dishonest and self-deception.
You have it completely backward, in fact in the culinary arts your greatness as a Chef is entirely dependent on being a manager of restaurant kitchens.
You get judged on the final end product, the full dining hospitality experience, as had by influential customers on a random night (like Michelin inspectors).
The food is just one factor of that experience, and the overwhelming majority of that food on any given night is not actually prepared by the chef with their name on the door, but by his/her staff (the AI Agents in this analogy).
If we want to stretch this analogy a bit - I believe all world-level chefs have a team of sous-chefs working for them. Doing things like chopping ingredients, prepping things, in fact probably doing a lot of th cooking. I think building with ai is pretty similar.
