This is what I'm wondering as well. Automation can do all sorts of cool things but my experience in manufacturing has shown me that machines break down all the damn time. When that happens, some poor tradesperson or engineer is under the gun to get it back up and running again because money is being lost by the minute. I'd imagine a machine running in a hot, greasy environment would need pretty extensive cleaning and routine maintenance to be reliable. Those things cost money and require diligent workers, and this is a company looking to lay off people that they're paying minimum wage.
