Millions of fast food workers will be replaced in the future by automated burger machines
I'd probably be willing to buy one at 1.5x the normal price if I could watch the manufacturing line make my burger. Even better if there are signs at each station explaining what it is doing and how the interesting part of the station works. for example, how they pick up a lettuce leaf at the condiment station.
Granted it is likely that even an automated burger joint would still need a small number of people, for things like unloading trucks, loading hoppers, fixing the machine when it breaks, cleaning the machine. I suspose i could a floor washing robot for the floors, but cleaning chairs and tables seems like it will be a long way off.
Lots of places are already semi-automated. Next time you are in a McDonalds, pay attention to the fry machine, most only require the human to add fries to a basket, and press a button. I'm not sure why they haven't gone a step farther, and decided to automate putting fires in baskets. they could use historical sales data, current orders, and what ever other info is relevant to adjust fry production so it would match demand very closely and reduce possible waste, and provide a higher quality product to the customer. I.E. hot fries.
