Hey do you guys know anyways businesses can try and protect their confidential information when utilizing a rag? Is it possible to do this

hi everyone, total beginner to Llamaindex and RAGs in general. I had a bit of a conceptual question I wanted to get your opinions on. With GPT 4 allowing images now, do you think LLM's will ever outgrow the need for programs like Llamaindex? Is there a world where GPT offers unified data handling and everything LI has?
