Half of the purpose of me documenting things is to make certain that I fully understand the problem and its solution.
As I write out the explanation, if something doesn't make sense, that is a prompt for me to dig in and understand more fully either what I am supposed to accomplish and/or how I intend to do it.
That applies to everything from single-line comments on up to project READMEs and polished, customer-facing documentation.
One consistent frustration I have had over the years is that so much code is not documented or (worse) poorly documented. If there is a silver-lining to AI-assisted programming, it is that clear writing of goals and proposed solutions are rewarded with more accurate outcomes. It should have always been thus. but I'll take it.
