>The fact that all the components exist but aren't in common use in delivery pizza isn't due to lack of innovation in the area, more likely it's cheaper with better throughput to have the labour of 4 pizza chefs rather than the expertise to keep an assemblage of these machines running in all the local pizza places.

I think this is what it comes down to. I was picking up a pizza at Dominos the other day, and while the girl was ringing up my order, she was also taking calls for orders and manually entering them into the computer. The workload for one person seemed absurd. I started wondering "why on earth doesn't dominos just staff a call center in India and have the orders forwarded to the store's ticketing system?".

And then I realized It's because that would be a cost center, and the food industry is already on tiny margins (<2%) as it is. It is simply cheaper and easier to offload all of that work onto a $9/hr employee you're already paying that will be replaced every 3 months after burning out. Modern capitalism has become brutally efficient at the expense of humanity.
