Personally, I think the ability to distinguish between all the knowledge that's overflowing is becoming a characteristic of the current establishment. In reality, the number of sites where you can get good information is extremely limited. It feels like we're in an era where discernment matters more.

Most of it is just misinformation, after all. People say knowledge shouldn't be restricted, but now we have the opposite problem. There's so much information that just skimming through it takes too much time. On top of that, as we shift from text to video, getting information has become even harder. Compared to text, YouTube videos feel like they have much lower information density. I've heard that the TikTok generation's text literacy is declining, but maybe that's actually a social adaptation to process as much data as possible from low-density sources

In that sense, the efficiency of RAG ultimately comes down to what kind of good knowledge you're feeding into the AI.
