I understand what you are saying, but you seem to be missing what I am trying to say: There are skills that cannot be replicated by machines.
All the products you are referring to are pre-processed ingredients. While the pizza machine can be loaded with flour, water, yeast, etc, it still needs all the other ingredients to be ready to use. It can’t make its own sauce or sausage or cheese or slice its veggies into various decorative shapes simply for the joy of doing so.
A machine can’t say “Hey, here’s a new ingredient, I wonder what I can do with it.”
All that is part of what being a chef is all about: the CREATIVE art of cooking, as opposed to the “slap it on some dough the way head office told me to” method of all fast food.
Yes, fast food workers will likely be displaced by machines, but servers and chefs in better restaurants are irreplaceable because of what they do OTHER than the simple production and delivery of food.
Not as soon as fast food/short-order or “Chili’s” style cooks, but never? I think you know better than that.
