@eeismann Interested to hear how you are measuring quality?

How do you measure Design productivity? The best I can do is "Overall PRs of the team / Design IC headcount." Any other means of measuring productivity? I'm interested only in measuring productivity, not quality (I have plenty of ways to measure that).

I’m a very patient person but if one of our engineers complained about being forced to properly align an icon at Apple I would probably not show the best side of myself. If your HI team tells you the icon is positioned wrong, the answer is, “I’ll go figure that out.”

A Norwegian neuroscientist spent 20 years proving that the act of writing by hand changes the human brain in ways typing physically cannot, and almost nobody outside her field has read the paper. Her name is Audrey van der Meer. She runs a brain research lab in Trondheim, and the paper that closed the argument was published in 2024 in a journal called Frontiers in Psychology. The finding is brutal enough that it should have changed every classroom on Earth. The experiment was simple. She recruited 36 university students and put each one in a cap with 256 sensors pressed against their scalp to record brain activity. Words flashed on a screen one at a time. Sometimes the students wrote the word by hand on a touchscreen using a digital pen, and sometimes they typed the same word on a keyboard. Every neural response was recorded for the full five seconds the word stayed on screen. Then her team looked at the part of the data most researchers had ignored for years, which is how different parts of the brain were communicating with each other during the task. When the students wrote by hand, the brain lit up everywhere at once. The regions responsible for memory, sensory integration, and the encoding of new information were all firing together in a coordinated pattern that spread across the entire cortex. The whole network was awake and connected. When the same students typed the same word, that pattern collapsed almost completely. Most of the brain went quiet, and the connections between regions that had been alive seconds earlier were nowhere to be found on the EEG. Same word, same brain, same person, and two completely different neurological events. The reason turned out to be something nobody had really paid attention to before her work. Writing by hand is not one motion but a sequence of thousands of tiny micro-movements coordinated with your eyes in real time, where each letter is a different shape that requires the brain to solve a slightly different spatial problem. Your fingers, wrist, vision, and the parts of your brain that track position in space are all working together to produce one letter, then the next, then the next. Typing throws all of that away. Every key on a keyboard requires the exact same finger motion regardless of which letter you are pressing, which means the brain has almost nothing to integrate and almost no problem to solve. Van der Meer said it plainly in her interviews. Pressing the same key with the same finger over and over does not stimulate the brain in any meaningful way, and she pointed out something that should scare every parent who handed their kid an iPad. Children who learn to read and write on tablets often cannot tell letters like b and d apart, because they have never physically felt with their bodies what it takes to actually produce those letters on a page. A decade before her, two researchers at Princeton ran the same fight using a completely different method and ended up at the same answer. Pam Mueller and Daniel Oppenheimer tested 327 students across three experiments, where half took notes on laptops with the internet disabled and half took notes by hand, before testing everyone on what they actually understood from the lectures they had watched. The handwriting group won by a wide margin on every question that required real understanding rather than surface recall. The reason was hiding in the transcripts of what the two groups had actually written down. The laptop students typed almost word for word, capturing more total content but processing almost none of it as they went, while the handwriting students physically could not write fast enough to transcribe a lecture in real time, which forced them to listen carefully, decide what actually mattered, and put it in their own words on the page. That single act of choosing what to keep was the learning itself, and the keyboard had quietly skipped the choosing and skipped the learning along with it. Two studies. Two countries. Same answer. Handwriting makes the brain work. Typing lets it coast. Every note you have ever typed instead of written went into your brain through a thinner pipe. Every meeting, every book highlight, every idea you captured on your phone instead of on paper was processed at half depth. You did not forget those things because your memory is bad. You forgot them because typing never woke the part of the brain that would have made them stick. The fix is the thing your grandmother already knew. Pick up a pen. Write the thing down. The slower road is the faster one.

I'm an absolute sleezebag with AI tools. Zero loyalty. Constantly cheating on them with the competitors. Suspect most people are the same and I have no idea how you build a good consumer product in this context.

🎯 When I got my first management role, the dominant philosophy was: - hire good people and get out of the way - coach don't manage It didn't work for me at all. The team's output only improved when I got in the detail of the work and injected some 'creative director' energy

Brian on why pure people managers won't survive AI: "I don't think people that only manage people will have any value in the future. Everyone's going to have to be a hybrid people manager or manager IC. In other words, even the managers need to code. You can't just be these managers where you're people's therapists and you're just doing meetings, just one-on-ones. People who have lots of recurring one-on-ones are not going to survive. That kind of leadership style is not gonna work. You need to have context. I hear about heads of design, they don't actually manage the design. Johnny Ive manages the design. He designs and he leads people. A design leader who only manages the people that's crazy to me. The way Frank Lloyd managed his design team is through the work. You don't manage the people, you manage the work. I think a lot of people will survive this age of AI. The two types of people that will not survive are pure people managers, and people that are rigid and don't want to change and evolve."

Every designer in the timeline praying that @Gregorein doesn’t open the hood on their side project 😝

@thenanyu @pdotcv I don’t think it’s that simple. Am sure most designers have experienced the ‘get back in your box’ pressure when leaning in to broader conversations in the org. Agree design has somewhat retreated from the wider scope and purview of past, but not purely by choice

If I had one big gripe with how we talk about these things, it’s that “design” is too narrowly conceived. Experiment design is design. Chip design is design. API design is design. We’ve boxed ourselves in so much that often I think designers don’t give themselves permission to think beyond visuals.

Put more bluntly, many designers I've worked with care more about the opinions of other designers than of their users. If you had to choose 1. designers think you're cool, but low usage 2. heavy usage, other designers think its lame which one do you choose? every PM picks 2

A part of the explanation… - Headcount decisions for design are usually made by product leaders - Product people naturally have a bias towards their own tribe - Whenever there’s headcount pressure/prioritisation guess which function gets squeezed 🤷‍♂️ (also applies to UX research)

The iPhones dominance may wane in years ahead, but it won’t because of this.

@balintorosz @benjitaylor OMG was thinking someone needed to build this the other day

One of the biggest area I’m working on right now is trying to bridge the gap between linear chat interfaces and the non-linear nature of human thinking. @benjitaylor’s Agentation already shows that markup and annotation resonate strongly with visual feedback, and I’ve found they feel more natural in text-based environments as well. One tiny step, but in the right direction. Coming tonight to agents.craft.do

Claude Code + xcode is insanely fun and powerful.

I genuinely think that coming on twitter back in the day made me smarter. Exposed to so many good ideas and interesting people. The feed now is full of trash/brain rot. I feel like I get dumber when I hang out here

Love this. Apprenticeship model is perfect way to learn product design. Hope this catches on with more teams as its rough cracking into the industry these days. I feel lucky someone took a chance on me back in the day despite my lack of experience/ qualifications

Love this chonky screen on the new iOS

@ariel_n @benblumenrose @designerfund Lol I have been thinking about this as well. Thought I was the only weirdo day dreaming about it! there’s an opportunity to mix screens with physical ctrls + use rive to build nice interfaces for the appliances. Incumbents are doing a terrible jon rn with controls/interfaces.

@benblumenrose @designerfund not even joking I messaged one of my close friends this a couple weeks ago

New dream brand designer role just opened up at Copper—a startup based in Berkeley building the most beautiful, battery-equipped appliances you've ever seen (and they're a @designerfund company as well). So much care goes into their work and they are incredible people...

@asallen heyjuno.co Havent tried it yet but saw the founder present and it looks legit. She’s from research background and they take the research methodology pretty seriously (have worked hard tuning the model so it doesnt ask questions that cause bias etc)

Anyone know of an AI interview/survey tool? Thinking of an AI chat-based version of Typeform that's a simple link with questions but can ask followups and get interesting responses.

Making some more progress on this little fella

been having fun playing in rive trying to learn how to rig a character. am using this polar bear which was shared as a community file and sorta reverse engineering it to figure out how it all works.
