> Does that mean you think a chain like Little Caesars, that offers about 4 types of "Hot N Ready" pizzas could basically automate away most of its workforce? If frozen pizza is possible, it seems really weird that no one has pursued this vigorously already.

Little Caesar's entire business model is "the lowest quality pizza at the lowest possible price". I assume they already have automated away most of their workforce; given a minimum wage, that's a key part of low prices.
