What it seems to me from the milieu of everything I've read and heard (that is: I can't cite examples, this is an aggregate developed from hundreds of articles and podcasts etc.) is that there is already an "AI" arms race underway, but that it has more to do with specialized ML systems than with consumer LLMs.
But I'm not really in the loop, and maybe OpenAI really is more important to the US DoD than Disney (as a stand-in for big copyright-based businesses generally) is to the politicians they donate to. But I dunno! That's why I asked the question :)
I would be more intrigued by the national security angle of this if copyright holders were going after, say, Palantir. But I just don't know how important they see these language models as being, or how interested they are in OpenAI's mission to discover AGI.
