I think we'll eventually move away from using these verbose documents, presentations, etc for communication. Just do your work, thinking, solving problems, etc while verbally dumping it all out into LLM sessions as you go. When someone needs to be updated on a particular task or project, there will be a way to give them granular access to those sessions as a sort of partial "brain dump" of yours. They can ask the LLM questions directly, get bullet points, whatever form they prefer the information in.

That way, thinking is communication! That's kind of why I loved math so much - it felt like I could solve a problem and succinctly communicate with the reader at the same time.
