Except ... when you look at the problem from a military/national security viewpoint. Do we really want to give this tech away just like that?
Yes. It is. I'm sure hostile, authoritarian states that are willing to wage war with the world like Russia and North Korea will eventually get their hands on military-grade AI. But the free world should always strive to be two steps ahead.
Even having ubiquitous semi-automatic rifles is a huge problem in America. I'm sure Cliven Bundy or Patriot Front would do everything they can to close the gap with intelligent/autonomous weapons, or even just autonomous bots hacking America's infrastructure. If everything is freely available, what would be stopping them?
Other than that there's also things like roformer, but I'm going to assume you won't count that as significant. US universities then certainly don't produce anything significant either though.

This tells me the extent of your knowledge about the challenges with these models.
