Automation is great. I do it all the time. Sure I could spend my life manually configuring switch ports, copying and pasting information into 50 pointless repositories, but that would be tedious, so I automate it.
Same in a shop. It's far better for a machine to stack a shelf than for a person to do it, it leaves the person free to do something more useful with their life.

And in this hypothetical, you'd be in favor of paying that person now, right? Surely the machine doesn't need the money in exchange for the value of its labor.
The scenario isn't "If you ask for more I'll automate you." It is that they'll automate them anyway when it is convenient for them to do so.
