A method for consuming books and other content by ear at multiples of normal speed, trained progressively like a physical capacity. The mechanism has two parts. First, comprehension bandwidth: reading is a highly computational behaviour where roughly 97% of brain function goes to decoding characters and only about 3% to comprehension, whereas listening inverts that ratio — 3% decoding, 97% comprehension. Second, evolutionary fit: humans have listened for hundreds of thousands of years but only read for about a thousand, so we evolved to be good at storytelling, paying attention, and processing with our ears; writing and decoding characters is an amazing hack, but a hack. Speed is then treated like resistance training — once you can bench 225 there is no reason to set the bar at 145, so you keep raising playback rate as capacity grows.

How to run it
- 1
Reframe listening as the native channel
Accept that reading is a highly computational behaviour and listening is what humans evolved to do. Outsourcing the decoding work to a computer is the same move as reaching for your phone to do long division instead of doing it in your head.
Pro tip The enabling condition is recent: AI narration was not good enough to read like a human until about now.

Start where you are and just practise listening faster
The trick is simply practice. Treat current speed as your working weight rather than a fixed limit.

Raise the resistance as capacity grows
Apply the gym logic — when you were younger, lifting 145 pounds was difficult; now you can bench it indefinitely, so there is no reason to set the resistance to 145. Increase playback speed as listening gets easy.

Use fine-grained speed control across media
Use a tool that increments in small steps — the guest uses a computer app called Video Speed Controller that adjusts in 0.1 increments — and apply it beyond audiobooks. His YouTube plays at 3x automatically; alone he would watch video at 5x; with friends he nudges it up 20% when they don't notice.
- 5
Calibrate against known human ceilings
Some people read at a thousand words per minute; a US college professor typically reads 330 to 350. Nobody objects to reading that fast. The upper level accessible to most people is much easier to reach through listening than through reading.

Route topics to the right medium
Use books for foundational groundwork on topics you know nothing about — there is no point listening to a podcast about nuclear if you know nothing, because you need the base before you can follow experts. Use podcasts where you already know the material and want the meta-level, or where you want cutting-edge material: the lead time from discovery to podcast is shorter than discovery to published book.
Pro tip Fiction and fantasy count — the world-building in sci-fi and fantasy requires real strategy to keep congruent and consistent, and delivers strong emotional rewards.
In the wild
The guest describes flying from California to New York and listening to Obama's book, written before he became president. The audiobook runs eight hours; at 2x to 3x speed he finishes it before landing. His framing of the value: it is like having sat next to Obama for the entire flight, except that Obama spent an hour thinking about every single minute of what he was going to say. He contrasts this with podcast economics, where roughly three human hours — one person interviewing, another being interviewed, another editing — compress into one minute of consumption, though he notes podcast quality has improved dramatically in the last ten months.
→ A full presidential-grade biography consumed in a single flight through speed alone.
The guest, who says he eats biographies for breakfast, argues most people already do intensive audio learning — with music. Hamilton runs two hours forty minutes and is, in his opinion, the best biography of Hamilton available: dramatised, but you cannot take away from the beat and the lyrics. Listening to music with attention to lyrics is exactly like listening to a book. He adds a side effect of heavy audiobook listening — you start noticing and remembering all the lyrics of songs, where most of his friends track only the beat and melody and need the lyrics on their phone. He wrote a rap album about Arnold Schwarzenegger's life after first hearing Hamilton.
→ Reframes audio learning as something people already do voluntarily for pleasure, removing the 'that sounds gruelling' objection.
Common mistakes
Treating current listening speed as a fixed ceiling
Speed is trainable capacity, not a trait. Leaving playback at 1x once it feels easy is like setting the bar to 145 pounds after you can bench 225.
Using podcasts to learn a topic from zero
There is no point listening to a podcast about nuclear if you know nothing about it. Books give the foundational groundwork that makes expert conversation legible; podcasts pay off after that.
Dismissing fiction as non-learning
The guest listens across fantasy, fiction, philosophy and sci-fi because it makes him happy and the joy from a book runs deeper than from a movie or TV series — and world-building itself carries real strategy worth studying.
