Yes a research focused system would be amazing. This is going to be very difficult though because it needs to be able to create context categories on the fly and recognize what does and doesn't go in them.

In a traditional system we tag documents with topics that they relate to. A language model like this though is more sophisticated than these tags. It would need to recognize which papers relate to the topic at hand to create a meta summary. Having it propose new research or give me insights is even more difficult because that requires it to understand the reality that undergirds the papers. Current a language model has no way to understand that Portugal is real but Middle Earth is not.

I do think that this idea is one of the biggest benefits that these systems can bring to society so I'm hopeful they can build it.
