Not necessarily. Consider a human assistant who performs repetitive tasks at an acceptable cost and accuracy while dealing with edge cases often autonomously.
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.
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.
