> Humans aren’t any better

We're different.

People have fairly consistent faults. LLMs are nondeterministic even in terms of how they fail. A high value human resource can be counted on to deliver. That, imho, is in fact one of the primary roles of good management: putting the right person in the appropriate position.

Process engineering has worked to date because both the human and mechanical components of a system fail in predictable ways and we can try to remedy that. This is the golden bug of the current crop of "AI".
