Automation is an example where it is shifting. A clear example of this is self-checkout at grocery stories or the use of robotics at warehouses such as Amazon.
A machine is not just its "management responsibilities". A machine is all of its parts. By shifting, I mean that some of the "parts" were people and are now automated or rely on robots.
Does it really make sense to say that a machine is not having its parts changed because its "management system" has remained the same?
