They do this already, but the problem is it takes me more time to verify if what they're saying is correct than to just use a search engine. All the LLMs constantly make stuff up & have extremely low precision & recall of information
I don't understand how that's an improvement over a link to a project homepage or a news article. I also don't trust the "verbatim snippet" to actually be verbatim. These things lie a lot.
Instead of the core of the answer coming from the LLM, it could piece together a few relevant contexts and just provide the glue.
