LLMs aren't finished products, though. And since they are basically a distillation of the collective works of all of humanity, it would make a lot of sense for them to wind up as public goods rather than some special advantage held by a select few.
Im not arguing that would be a bad spot eventually, like water or electricity distribution. Right now it's a highly Dynamic field though and changing On a monthly basis. I don't think it makes sense for the US government to try to Duke it out and drive all of the competitors out of business.
