A company like Amazon doesn't treat its warehouse workers as human beings. Workers are seen as disposable: forced to piss in bottles, forced to work around the corpses of their collapsed coworkers, paid the absolute minimum possible, and replaced the second they don't operate like a perfect unfailing machine. You aren't viewed like a human, you are a tool. Cattle. A piece of meat they are forced to retain because a robot isn't quite capable of doing your task yet.
The article's use of "meat shields" isn't any different. Humans are going to be hired for the sole reason of taking accountability for actions dictated by AI. They are there only because the company can't put blame on a machine and will be sued to oblivion if there's nobody to blame at all. Your existence as a person is irrelevant, they are just interested in someone with a heartbeat they can blame when stuff inevitably goes wrong.
