Not sure if that's true, there's some frozen supermarket pizza now that's seriously good. If I ordered fast food and they delivered a freshly baked Crosta Mollica pizza I wouldn't send it back. Of course a fresh pizza is better, but imo you couldn't get a Crosta Mollica quality frozen pizza 10 years ago.

The pizzas I've been buying in Tesco are quite good really like this lot https://www.independent.co.uk/extras/indybest/food-drink/bes...

apparently they are "hand stretched" but I presume much of the other processes are automated in a factory. (prob not AI robots). A lot is about the quality of the ingredients. Those are wood fired and not frozen.

Guys look! An American up there

Those factories still have people stretching dough, while the bases travel along a big belt, because human hands are good for that task, and are widely available and easily repaired or replaced, and adapt to different shapes and sizes of product and other contingencies.

Are you talking about frozen pizza? That's always rather disappointing. Even chains like Dominos let alone good local pizzerias make their pizzas to order by people.
