A lot of times human commands are prone to errors / edge cases as well. Example a simple git pull command usually would take < 7 seconds, but then LLM can take care of resolving merge conflicts etc as well.
A simple git push is usually instant but that comes with an overload of some un intended changes being pushed, which LLMs take care of removing themselves.
When LLM is doing its thing, we can spend the same time in writing the next prompt.
