The most destabilizing stuff has been from internal actors and they didn’t need AIs for that.

I do think there’s some cause for concern in that foreign actors who previously had a difficult time producing useful (for their purposes) English-language content may have an easier time now that they have Large Language Models (LLMs). But there are still going to be barriers.

You would still need fluent English speakers to prompt the LLM, check the output, and edit it. Even native English speakers trying to get an essay out of ChatGPT often can’t use the raw product without reworking it a little. Someone who speaks little or no English trying to use one of these to write English disinformation is only going to get the “right” disinformation by accident.
