If chatgpt is scraping the web, why can they not link tokens to source of token? being able to cite where they learned something would explode the value of their chatbot. At least a couple of orders of magnitude more value. Without this chatbots are mostly a coding-autocomplete tool for me—lots of people have takes, but it's the tying into the internet that makes a take from an unknown entity really valuable.

Perplexity certainly already approximates this (not sure if it's at a token level, but it can cite sources. I just assumed they were using a RAG.)
