I can start brushing my teeth 30 times faster but it won't change my life. This is nice for RAG but it's a very localized improvement. And 30× sounds big but is just an order of magnitude improvement also.
Brushing your teeth is not central to your life, recalling facts correctly is, and a 30 fold improvement in the latter very well could change your life. I'll leave it to you to figure out which is a better analogy to RAG.
