Say what you will about Google, they generally credit their sources. Yes, it's part of their advertising model, but it's still a Very Good Thing.
I hope that Google's plan is to release something that continues this model. If it's near as good at ChatGPT and strongly includes sources, it is the right future.
How it actually works is more like:
1. User asks "What's the tallest building in the world?"
2. MS, rightfully, assumes that GPT has no idea what the answer to this is. And even if you trusted it to know, it will always lag behind and new buildings could have been built since then.
3. MS searches their index for the most relevant document snippets related to this query and feeds it to GPT as context.
4. MS asks GPT to answer the question in the context of those document snippets.
5. MS returns the result from GPT along with references to the documents it sourced the information from.
This is how the OpenAI /search endpoint used to work.

It's probably not too hard for them to tune ChatGPT and the upcoming GPT4 that way, and I think it's very likely they will do something like that in Bing.
Can you elaborate here? (Honestly asking since I'm not seeing the similarity)
