With all the growing responsibilities of running a startup, I find myself frequently, and sadly, neglecting Pocket Rocket. This is bittersweet, but I want it to find a new home, and a worthy owner for it. Pocket Rocket is loved all around the world, but I haven't been able to support it properly for years now. It has so much potential that I'm squandering. It's been at the top of the App Store, it's been showered with praise from Apple, it's a favorite of many teams at SpaceX. If you feel up to the task of shepherding this lovely product into the future, reach out. I want to find a worthy owner.

I think everyone spends 2 hours in front of opus and then assumes that professionals are cooked. Those professionals will spend 2000 hours in front of opus and you haven't seen what they will make yet.
Ever wonder what $1874.40 of Opus 5.5 tokens looks like? Wonder no more. I highly recommend watching the whole video on 1080p on a large screen with sound on. Pay attention to all the little details. - Birds flying and diving into the ocean. - Cloth, signs and lights swaying in the wind. - Crabs scuttling along the shore and burrowing when you get close. - Fish swimming alongside the whale. - Lights illuminating the dock at night Then zoom out and see the entire island. Never dipping below 60 FPS at 1440p resolution. Yes, there's a few bugs and visual artifacts, some textures need improving, the shorelines waves sometimes look funny, but these are so trivial to fix at this point. FYI I'm on the $200 subscription plan. This used 59% of my weekly usage and took 2h 7h of API time using multiple subagents, about 8h in real-time. There was extremely little technical direction here. 99% of my prompts were "Add X and Y" or "This looks weird, make it better". It's a great time for hobbyists, bad time for professionals. This experiment has further cemented my view that technical creatives are about to experience a massive disruption.

True for all disciplines of art! Concept, video, game design… the tools are multipliers on underlying talent
3D artists are better equipped to leverage AI for 3D creation than non 3D artists, just like developers are better equipped to leverage AI for coding than non developers

“the mechanics would not be possible without ai.” This is the second time this week I’ve seen something that felt special. Are we finally getting past “I oneshot this game” and getting into the real uncharted waters of innovation with ai games? I’m so excited for what’s to come.

I went back to read an old three-line poem I posted on medium years ago and they plastered a giant ad between the first and second lines. Now I’m migrating all of my writing to self-hosted. Ev’s founding promise that “Medium lets you focus on your words” was so beautiful and so long ago.

Here's an early game trailer of Cook the Dungeon (🔊Sound on), a first-person roguelike deckbuilder where you defeat monsters, harvest their parts, and cook meals for the battles ahead. If the game interests you, please wishlist the game on Steam! It helps the game to get discovered.

We’re starting to see some real game design innovation with AI in the loop. That’s way more impressive than the gauntlet loop stuff, even if the tweets aren’t as likely to go viral.
Hey everyone👋 We'd like to introduce our new game @dartwords, the word game that responds to you! dartwords.com

A Data Center Came to A Small Town. You’ll Never Guess What Happened Next* *unless you guessed lots of jobs, lots of tax revenue, spillover benefits to local business like hotels and restaurants, discounts on electric bills, and grants for teachers.
My latest column: On a recent family trip to Aberdeen, SD, it was nearly impossible to book hotel rooms. Why? A 400MW data center in Ellendale, ND, pop 1100. Overnight, rents have doubled & the town’s pop has tripled. Welcome to the new American frontier: sfchronicle.com/opinion/arti…

The models recommends the party because the party writes on the internet. As Tyler Cowen first wrote back in January ‘25, you should be “writing for the AIs.”
Why do major AI models tell left-wing voters in Japan to vote for the communist party? My new research paper led by Sho Miyazaki. In 2026, voters across the world will be asking AI to help them vote. How will the AI respond? We study this question in Japan, which recently held a snap election. When voters provide policy positions, we find that the models rely heavily on this information—and in Japan, the models heavily recommend the communist party in response to left-wing positions, even though the positions we provided are held by a range of other parties. Why are the AIs doing this? We’re not sure, but we have a theory: in Japan, the communist party operates a content-heavy, fully open website with a “newspaper” that is openly accessible for AI models. In contrast, many Japanese news outlets block AI models from accessing their content. The result: the Japanese Communist Party website is one of the most-cited “news sources” in our study. This pattern of recommending the JCP is consistent across many models, including the most recent frontier models. There’s much more work to do here, but we think our paper suggests two main takeaways: AI models should be more careful about what sources they consider news, maybe especially in non-US contexts where the model companies may hold less policy expertise Parties and news sources that want to influence AI recommendations should think twice about excluding their content from AI. To paraphrase @tylercowen, when it comes to elections and voting, journalists may want to “write for the AI”! Governments may want to consider policies that allow this content to be used for voting recommendations but not for other AI model use cases. Looking forward to everyone’s feedback as we prepare to submit this paper and turn to studying US voting recommendations in advance of November’s midterms. Check out the full paper below.

I got to listen to Patrick speak on this topic last week and was pleased to hear him take such an expansive view on the topic of aesthetics, in particular, his examination of culture and the demands it makes on those who supply the built environment. There’s a lot of talk recently about the wealth created in SV and the apparent lack of patrons of the arts relative to the magnates of old, and it’s my belief that this is at least partly downstream of a cultural shift away from celebrating these patrons - see the refusal of SF and Chicago to play host to the new Lucas Museum. The Germany example is a perfect and hilarious example of the demand effects towards worse outcomes. What seems clear to me is that there is an interplay between supply and demand. What can start as supply side issue, an externality that first creates the conditions for lower quality goods, soon becomes an expectation that leads to lower demand, creating a cycle of ugliness. I’m pleased that some of our sharpest and most vocal thinkers are engaging with these questions head on. I hope it’s the beginning of the cycle reversing, I look forward to a more beautiful future.
Someone asked me recently why I’ve become interested in aesthetics after having spent most of my life more interested in STEM-adjacent topics. I hadn’t really considered the question consciously before, but I’m certainly thinking about aesthetics more than I used to. I think it’s a confluence of things: • Many things today are ugly and far uglier than they used to be or need to be. Once you see this, it’s kinda hard to stop perceiving it. (Early twentieth century phone boxes versus modern phone boxes; old water fountains versus new water fountains; etc.) As someone with a naively meliorist assumption that most things should be getting better rather than worse, it’s all a bit perplexing: why did we stop doing things nicely? Is it a choice? Was there a malevolent spell cast upon us? This vein led me to think more about modernism and why much of art became more intentionally "challenging", grotesque, opposed to prettiness, rebarbative, dissonant, etc. Can or should anything be done about this? Is this just how things ought to be? • Relatedly, much of modernism involved a kind of explicit repudiation of cultural continuity and represented a schism with prior practices. This is maybe most evident in American architecture, where the International Style exhibition in 1932 initiated the displacement of a rich tapestry of prior styles. This cultural break seems important and interesting to me, and I suspect that the rejection had important consequences outside of the aesthetic domain. Samuel Hughes has been exploring this question in his recent writing at @WorksInProgMag; @RuxandraTeslo is also pulling on this thread. Elaine Scarry wrote about how beauty inspires creation. If so, the inverse may also be true: ugliness inhibits it. • It’s clearly the case that changes in the aesthetic domain can at least inspire progress in other places. Petrarch helped set some of the preconditions for the Renaissance which in turn fostered the scientific revolution and Enlightenment. Things like World Fairs (the 1851 Fair at the Crystal Palace recorded 6 million admissions when the population was 21 million) reflect the popular interdependency that used to exist between aesthetics and material development. • @tedgioia and others have written about stuck culture and how so many domains seem to have ceased to straightforwardly advance in the way that they did up until the nineties or thereabouts. This is obviously peculiar and interesting. What changed, and what does it mean? Is it about the internet and fragmentation? Is it about a loss of supply? Is it just about having reached the zenith of various mediums? • I’m generally interested in markets and the dynamics of creation. In aesthetics broadly, I find the reflexivity between supply- and demand-side factors to be very thought-provoking. There’s a natural desire to view satisfaction of individual preferences as the yardstick to measure market success, but things get interesting and even a bit unsettling when we start to think about how the supply might start to shape the demand. I often think about this in the context of food. Why is food so much worse in Germany than many of its neighbors? Germany certainly doesn’t have less material ability to produce good food; indeed, Germany is richer than the countries around it. There’s probably something about German food supply chains that is impoverished relative to France and Italy, but the Germans themselves don’t seem too upset about it. It just seems that the Germans are stuck in an objectively worse market equilibrium than their neighbors: the food is bad and they’ve gotten used to it. The obvious question then is where else these kinds of reflexive patterns apply, and where else we’re stuck in some objectively inferior equilibrium, even if preferences are in some superficial sense being sated. • While this is an extremely banal and obvious point, I hadn’t until recently thought much about or internalized how much one can study reasonably objective things ("the status of women in society", say) through artwork. (Thanks to @_alice_evans for opening my eyes here.) In this vein, I’m pretty excited about the possibilities over the coming years in computational art analysis. I want something that’s conceptually similar to Google Ngram timelines but for the visual arts. • We've always tried to do things well at Stripe. I've come to see that attempting to do them beautifully is often a helpful way to break out of standard practices and to do something with greater novelty and in a way that might have other benefits besides. (Also, excellent people want to do great work because it is intrinsically satisfying. Explicitly allowing aesthetic considerations to carry weight avoids having to justify every assessment with some kind of torturous empiricism.) • In his Nobel Lecture, Solzhenitsyn said that, among the Platonic virtues of goodness, truth, and beauty, that beauty is special, for it possesses a unique kind of irrefutability. He notes that arguments, writing, and philosophical systems can all be predicated on misapprehensions, but that “a true work of art carries its verification within itself.” He proceeds to observe that when goodness and truth are threatened, the “ever surprising shoots of beauty will still force their way through.” There is a lot of specious and motivated reasoning in the world today and plenty of questionable value systems. I don’t think that beauty directly reflects any definitive trait, but I’m intrigued by the idea that it can be a marker of deeper metaphysical coherence.
