Thanks for spotting this and pointing it out.

I'll take your word for it about Kurzweil. The wiki also says "a director" - good catch.

Here's what google says about Norvig though: http://research.google.com/pubs/author205.html

FWIW, I don't think reporting to higher ups (e.g. VP, SVP) precludes someone from being "the director" if there are no other people in the department with this title / position.
