If we want reliability - we come up with processes to make it reliable and not rely on individuals getting it right. Code is a way to create a reliable process in the digital world.

Maybe acceptable in some cases but the original example in this thread was about accounting and they use software to do the counting not humans.

And even id humans/llms do it there would still be a need for systems of record with things like audit log etc.

For some things that's acceptable or even good. If I want to add up a list of a million numbers human assistants aren't bringing any advantages though.

I'd like to apply for this job where I can make mistakes and it's considered an acceptable cost. Seriously, I can't remember the last time I made a significant error and it was acceptable. Maybe during training? Half the effort in any job is literally verifying correctness.
