I can walk through my local woods and listen very carefully but I don't think I could read a recipe book and pay attention to an audiobook!
So for me and I guess for most people it depends on the intensity of the activity and on the nature of the book. I have gradually found where the balance is for me and I've learned to hit the pause button or rewind 30 seconds.
I also pick different types of books to read and to listen to. I _love_ having an engrossing story as an audiobook. And popular science is a great listen, e.g. I loved the audiobook of Stolen Focus. But with physical books I tend to choose more involved or complex novels (e.g. Deep Wheel Orcadia), poetry, and for non-fiction books that are more specific to my interests (psychotherapy, ceramics).
This appears, to me, like an LLM-agent descendent of these earlier multi-agent systems.
I lost track of the research after I left academia -- perhaps someone here can fill in the (considerable) blanks from my overview?
