Automation may seem unintuitive economically but the alternative is much worse.
Food workers tend to be minimum wage workers. Minimum wage really stands for minimum living wage which is different from place to place and somewhat artificial (e.g rent). If minimum wage workers could be paid less, the "owners of capital" would (because they don't generate that much value)
Example: if you order a 9$ burger and it costs 5$ to "manufacture" a burger (food processing, shipping, preparation etc.) and 4$ to have a minimum wage workers assemble it; by eliminating the minimum wage worker, eventually the price of the burger will go down.
But who will buy burgers? Automation/technology is about turning goods into commodities. Eliminating scarcity.
So, yeah, I would work for the guy killing minimum wage jobs because without him, 10-15 years from now, you'd be paying 25$ a burger and most of it will go to the minimum wage worker making 15$/hr doing a job a machine could do.
I won't bother to argue how mind numbing those jobs are.
