Bad documentation has been out there for as long as I can remember. The problem AI seems to be adding is the expectation of “just ask an AI” which is removing the drive to write even bad documentation and expecting the AI to derive answers from code and API references.

No MS, I don't want to ask co-pilot. Why don't you get co-pilot to draft some good documentation, that you then review and edit to make sure it is accurate, instead of expecting every individual to ask an AI for every question they have? That would be a lot more efficient in terms of energy use, I expect.
