Jordan Peterson and Vivek Ramaswami talk about attention span.

This is extraordinarily insightful:

Peterson observes that the idea that attention spans are shrinking fails to account for the widespread consumption of audiobooks and very long podcasts. Ramaswamy first responds by speculating that there's a kind of "low-level dyslexia," and most people are a little slower reading than listening, and that means they are really capable of absorbing more complex material than they're willing or able to read.

Ramaswamy immediately posits a second theory: There's a hunger for "human connectivity," and people want a "disintermediated relationship" that they get from hearing the voice of the person who is generating ideas. Peterson jumps on that: It's why unscripted podcasts work so well. Peterson says books can go deeper, but it's easier to deceive people with a book. You can "craft your lies." But with a podcast, you get spontaneity, tone, and demeanor. People experience Joe Rogan as "genuine." "It's the antithesis of the crafted Hillary-Clinton political-class message." It's why Donald Trump was so successful. 

I'm just summarizing (as the presence of Abraham Lincoln in my tags hints), and the conversation continues. I haven't set an end point. You'll see how long your attention span reaches.
