I'm just starting adding a list of the members of the (US) National
Academy of Engineering. we have only about 1% of them covered by
articles. there are dozens of fields like that where we haven't even
begun on the obvious. We have probably a similar coverage for pre 1990
US state legislators in almost all states.
Additionally, for creative work, for politics, for important products,
there will always be subjects for new articles. People are not going
to stop doing new things.
What we need is people. We will get them when we stop discouraging new
ones by our general hostile way of talking, and our focus on deletion
rather than improvement for new articles. Anyone who comes to write
even a facebook-type article on themselves is a potential recruit, if
talked to carefully. If they're willing to go to the trouble of
writing, and brave enough to do so, they can be guided to find a
proper subject.
