Airbnb stuck their entire customer journey up on their office walls.

Drawn by a Pixar animator, pinned where everyone walks past them daily.

30 frames.
15 for hosts.
15 for guests.

They call it "Snow White."

Chesky stole the idea from a Walt Disney biography in 2011.

Every new product idea has to answer:
→ "Which frame does this serve?"

If it fits a frame, that determines the owner, who prioritises it against their KPIs.

If it doesn’t fit a frame, it doesn’t serve the customer, and doesn’t get shipped.

open secret in the valley that design, taste and aesthetic data is being scaled up massively at one of the big labs.

for those on the outside, look at the hiring, the contractor posts, the silence from the obvious incumbents.

slides first. docs next. marketing, reports, anything visual after.

canva ipo doa. $ADBE is in trouble.

and remember: visual tokens decode 10-50x text. kv and compute bids haven't shown up yet.

Imagine every pixel on your screen, streamed live directly from a model. No HTML, no layout engine, no code. Just exactly what you want to see.

@eddiejiao_obj, @drewocarr and I built a prototype to see how this could actually work, and set out to make it real. We're calling it Flipbook. (1/5)

It has been so much crazier than just this. The tell all books in 10 years from every corner of industry will be something else

this was such a pattern at Google circus 209-2016 they had to actively stop acquiring companies started by Xooglers to disincentivize it

Went down the rabbit hole on this. Your brain treats a physical book like a landscape. It builds a spatial map of the text, the same way it maps trails, rooms, and city blocks. When you scroll on a phone, that map breaks apart.

Seven large-scale research reviews and direct brain scans confirm what you already feel.

A 2023 study in PLOS ONE attached brain-activity sensors to children’s heads while they read the same text on paper and on screen. Paper reading produced fast brain waves, the pattern linked to focused attention. Screen reading shifted the brain into slow waves, the pattern linked to mind wandering and daydreaming. Same kids. Same words. Measurably different brain states.

A separate 2022 study from Showa University in Japan scanned the front of the brain, the area that manages focus and comprehension, during phone versus paper reading. Smartphones sent that region into overdrive, meaning the brain was straining just to keep up with basic processing. Paper reading produced a moderate load that triggered natural deep breathing, which helped regulate brain function and sustain focus. The phone suppressed that breathing pattern entirely.

Since 2017, researchers have published seven major reviews combining hundreds of individual studies. Six of seven reached the same conclusion: people understand less on screens. A 2018 review of 54 studies and 170,000+ participants, literally titled “Don’t throw away your printed books,” found paper outperformed screens across the board for non-fiction. A 2024 follow-up with 49 more studies confirmed it. The gap has grown steadily every year since 2001. Being a “digital native” doesn’t help.

The best explanation is how your brain tracks where you are. Your short-term memory can only juggle about 7 things at once. A physical book gives you constant location cues: the weight shifting from right hand to left, where a paragraph sits on the page, how thick the remaining pages feel. Your brain hands off the “where am I in this text?” job to those physical signals, leaving more room for actually understanding what you’re reading. On a phone, every screen looks identical. Your brain has to track position and process meaning at the same time, and something gives.

A Norwegian eye-tracking study analyzing 25,000+ individual eye movements found screen readers processed text more shallowly. The students had no idea they were reading differently.

In 2019, nearly 200 reading scientists from 30+ countries signed an open letter warning that screen reading was degrading deep comprehension. Since then, Scandinavian countries, among the most digitized school systems on Earth, have started putting physical books back in classrooms.

I know this has already been said a million different ways, but it's increasingly clear that playing it safe with your career right now is the riskiest thing you can do.
