Some big personal news: I’ve joined the Design Team at Apple. So excited to work with the very best team in the world on my favorite products. ✌️

@MengTo Happy birthday! May your hit target expand into the most highly accessible values

Turning 44 today. Yep, the perfect iOS button size. I know I'm a geek, but that's what makes me human. AI can amplify that, but it can't replace it. A few things I've realized: - I've never enjoyed work more. - I spend way more time with my kids. - My agents handle the work I hate. - Agents are upgrading from assistants to managers and advisors. They have subagents. I'm becoming an architect of agents. Like in The Matrix. - I can finally be productive while traveling in Japan. Taxi rides, long lines, awkwardly waiting for stuff... I just talk to Codex via my iPhone. - I can build design tools I could only dream of before. It often starts with a single open-ended prompt, then my agents explore ideas, spawn the best into threads, self-verify, and bring me screenshots and videos to review. - Design is still my moat. Every place I've lived, every button I've pressed, every mistake, every failure, every win has shaped how I see the world. Agents can't manufacture that perspective. - Intuition is still my biggest advantage. It lets me make thousands of decisions effortlessly and keeps my agents unblocked. - My team is more independent than ever. They're building their own tools, growing their own YouTube channels and X accounts, and running fleets of agents. They'll surpass me one day, and I'll know I did my job. - Everything is moving insanely fast. Instead of trying to keep up, I ask my agents to learn it first, then teach me. It feels like Neo downloading kung fu. Having the time of my life.

@Robscholten_ @Crime_Penguin previously, it was just who I followed. With the algo timeline it's extremely heavily weighed by iOS based sharing as far as I can see, so whatever you tap share on will get boosted hard. Likes are a lower signal but also works.

@sdw @Crime_Penguin How did you manage to do this? My timeline is already much better, although it’s still not fully focused on the people I follow and their type of content (product design)

Twitter was great because individual users got the timeline they chose. It was a content brokerage, allowing the user to build their own highly-tailored and networked platform. Now “X” users get the timeline Mr. Bier wants them to have, and that’s why the app is dying.

@james_im Those are fun bikes

Capture anything in 3D with a single iPhone photo

Rise and shine.

@tylr congrats!

new job this week

Today’s recommended read for designers. Note that some of this applies to glyph iconography too!

@rickie Susumu is the goat

Making some folders that look like Susumu Yoshida's Smooth Leopard set

@antoniogm the dakar malle moto would like a word

My big contrarian take is that rally car racing is the last real form of motorsport.

@jpteasdale @shiraeis forward deployed personality

@sdw @shiraeis I—also—will put “frontend personality” in my bio.

Many ppl in sf develop their personalities via distillation attacks, & most aren’t even distilling from a frontier personality, just distilling from a distillation… & ya know what happens to a model trained on synthetic data for 4 generations. This is why few ppl here have taste

Public betas are live! 🚀 More responsive, reliable, and delightful. Tap into the all-new Siri AI, transform your images with new Clean Up and Extend tools in Photos, and so much more.

@jeffmihaly beautiful shots

Portraits of Yosemite

@sushrutabasak gowalla spotted @maxvoltar / @jw

all first chapters from a 2010 map. often forget that sam’s loopt was quite big to show up in almost every map of the social web back then

@radbackwards insanely good

Starlink on planes changed my life. We should equipped all planes with this immediately.

@existentializzm place is great. made me a believer in porridge. also pølsehorn are legit

Kantine is legit, def rec if you’re looking for Scandinavian food in sf

@jenny_wen @cursor_ai big moves! congrats on all of it :)

ok! quick updates from me: - i left anthropic (who does that?!) - had a baby (i love her) - and am joining @cursor_ai as head of design (eep!) it's been a low-key dream of mine to nurture a team that cares so deeply about craft, quality, and building great tools. very excited!

@__nikitha I keep telling people this. nothing better.

linea is the best coffee in sf and their beans are from god

@luisgnet yep

@sdw wait seriously??

which one of you sf nerds has a flipper zero I can borrow for a day to program some new T5 transponder keys???
