Good question. I used to read for the love of books and building a fictional world in my head. I do enjoy that from time to time now, but the nature of the value I derive from reading has shifted.
Using your analogy, it’s just that instead of frequenting art museums like I had before, now I have expanded my interests to business presentations, hackathons. Both generally provide audiovisual material, but we go to each of them for very different reasons.
Primarily biographies(to see how the world looks like from someone whom you admire), business, and psychology books. These tend to provide techniques that seem unusually enlightening at the start, but require conscious application over the long term for one to reap real benefits.
