I would think that the biggest problem in this type of old commoditized industry (food) the biggest problem is how to sell. The cost of making lots of pizzas, with robots or humans, should be less in total than the cost of marketing, delivery, etc. Maybe that's the answer to this question. These robots are there to make these pizzas appealing to investors (hi-tech something something), and then prospective customers (a hi-tech pizza that doesn't taste like shit)...
