I wonder what part of these failed sales is due to GDRP requirements in the IT enterprise industry. I have my own european view, and it seems our governments are treating the matter very seriously. How do you ensure an AI agent won't leak anything? It just so happened that it wiped entire database or cleared a disk and later being very "sorry" about it. Is the risk worth it?
I think there is distinction between documentation in development progress and documentation afterwards. IMHO article is about the first.
After something is done, you can write thorough documentation of product with UML diagrams and whatnot.
