Algorithms can blindly follow through into an obviously illogical decision in ways that a human brain doesn't (and when it does, we consider that person unfit for a job as well).
I maintain that the core difference is the way these technologies are being deployed in a centralised fashion by human organisations, but the technology itself is no less capable than actual human decision-makers.
In other words, if you do believe that humans can be illogical, then who told you the human thinking doesn't come from an algorithm itself (of e.g. NN nature)?
Not that this is not needed, of course, because what I wrote is much easier to achieve. I wrote that "Algorithms can blindly follow through into an obviously illogical decision". That doesn't even need the algorithm to be illogical itself, but just to arrive at an illogical (obviously for us, humans) decision. It can still arrive at that logically. E.g. if I program a simple algorithm that "if the car sees a zebra crossing, go full steam ahead" the algorithm will do just that, whereas most humans would question it.
