How long have "large scale RAG systems" really existed in the first place? I'm always surprised at this, given how new all this really is, relatively speaking.
my personal experience - I have been involved with such projects for the last 2 years. interestingly enough, a lot of times such initiatives didn't take off because people/stakeholders were overcomplicating things and wanting to use semantic search for everything - without having a minimum knowledge of chunking strategies, pros/cons etc
