Fantastic article, thanks for sharing. Also, this little bit, "... I really wanted to talk about WarGames because it’s the one movie I can think of that’s had the most direct influence on any technology policy issue." made me think of another film, which I would argue had a great effect on technology policy. The film was Disney's "Victory Through Air Power" [1]. (See, specifically, the "impact" section [2] of the Wikipedia article.)
The film is an astonishing piece of animation (which in places resembles an almost manga style), education and propaganda. I cannot recommend it highly enough and it is available at the Internet Archive [3].
