I don't think so. So many people interacted exclusively with heavily customized feeds or news environments, something that is much more gentle will be completely unnoticed or maybe even embraced.
> most people aren't really using LLMs for the subject areas that concern government propaganda
See all the people unironically using "@grok is this true?" It doesn't have to just be government propaganda (eg did Nixon break into Watergate?), it is more about shaping the boundaries of a conversation, framing, etc.
> You seem to be envisioning some kind of a world where people don't access the news or social media directly, but it is somehow passed through some kind of LLM transformation filter.
I envision a world where most people take the path of least resistance. They will not explicitly sign up for it, but will gradually shift to reading the easily digested stuff first. Look how popular tiktok is, the popularity of summarized info, etc. In that summarization and aggregation, there is plenty of room to steer a conversation or influence thought, especially over a large audience.
There is nothing here that will be an overt smoking gun, just a systematic bias towards a particular idea, thought, etc. Hard to prove and even harder to know it's happening.
