At least with a fully human chain of responsibility, the buck stops with someone

A computer cannot ever be made to atone for it's misdeeds

Humans can

Someone has never encountered bureaucracy I see. Human chains of responsibility manage to dissolve blame into nothingness all the time.

Blame is not the same thing as accountability

In situations where accountability is absolutely required, you will find that people are held accountable

Often they are scapegoats, but that is a different problem

Having a scapegoat take the fall doesn't count as `accountability` in my book.

Not really. The vast majority of adults are not at all accountable in today's society. We blame.

Aka the Nuremberg defense; sometimes it works, sometimes not so much.
