Then how have humans ever accomplished anything?

Can you explain your reasoning? I don't get it at all.

Humans communicate in natural language. When a CEO or project VP commands to have something they want produced, they're not using any kind of "reliable/stable" exact language. They may barely be able to even use a computer, much less write code. Nevertheless the final production product is still completed.

When the end product is supposed to have any semblance of reliability and durability, even human beings do not communicate in natural language.

As an example:

- Science: Many non-natural languages and notations used for communication, math being the most obvious.

- Laws: Looks like natural language when you squint, but actually very rigid and un-natural.

What does that have to do with the CEO I mentioned? They're not writing math or legal documents, yet their wishes are still materialized. Whatever the intermediary processor utilizes is unimportant.

It's an example of large domains where natural language does not work well enough, as a counterpoint to the arbitrary, niche CEO example of a situation where it might work. It is responding to the entire thread, not just your comment.

How do you plan to update such natural language code? Words change meaning. This is what I meant by stable
