There's a limit, though. Not only are there mandatory breaks for truck drivers, but also a maximum number of working hours my boss is allowed to demand from me. And even within those limits my boss is not allowed to dispense cocaine during tight deadlines.

We do have limits for how much work a human is allowed to do and, based on the experience of Amazon workers, they are due for some tightening already. I'm not seeing a clear case for AI but I wouldn't discount it entirely either.
