This is true, but up until about two and a half years ago, we built IT systems to be more reliable, consistent and auditable than humans, and to provide some security guardrails on human malfeasance.

Now we're OK with building systems that are an order of magnitude faster but behave no better, because what?

Because humans have basic needs like food, shelter and they can be put it jail. And they have loyalty, patriotism, feel part of the society. Those threats & incentives have made it for a good society to function so far.
