No the stupid thing is not understanding how Moore’s Law applies. More processing power and more memory means being able to program more actions and knowledge. It’s very simple, and you should be embarrassed to not get it.
Automation of these jobs is inevitable, but raising the cost of the workers hastens the day. It means the robots can be more expensive and still cheaper than the workers, because the day they’re cheaper than the workers the workers are gone.
Ok this is stupid. Currently the average price of labor is 25% for fast food. Automation may cut that in half to say 12.5%. The upper limit of savings is 12.5%. So most of that will go to profit with some, maybe, 5% going to the customer. This is a way to increase profits marginally. It has little to do with reducing the retail price of your hamburger.
