Employee costs vary greatly depending on where the factory is located. Here in Italy, a line operator costs around €60,000–70,000 per year, and half of that goes back to the government for public welfare redistribution.
Robots costs have a fixed CapEx that humans don't have. If they become expensive you can move the factory to a cheaper nation.
People keep saying that a humanoid robot will cost around €30,000, but is that just for the hardware, or does it include all the additional services required to operate it? Will they be as interchangeable as humans, who can be reassigned to a different task in 30 minutes without notice?
Honestly, it still doesn’t make sense to me; to use an analogy, it's like you're building and "horseless carriage" instead of a car.
