From the user's perspective, sure. Or when a particular product or version ships, then it's "done" as far as that version is concerned.

But from the maker's perspective... nothing will ever be complete. Even in the most meta sense possible.

Philosophy is fun :)

I work on a FLOSS data center management framework. 13 years ago, while at the office preparing to configure a new server, I had a flash of insight seeing the entire data center managed by such a tool. I saw it complete in my head. And since then, I'm still working towards that goal, that I'll never really reach.

Right, I think Brooks means “the act of creation” here, rather than “the product of their creation”.
