I learned this the hard way: do NOT use SwiftUI if you want your app to look and feel amazing. At least when coding with AI. (sorry, Apple colleagues reading this 😅) I'm sharing my process vibe coding this calorie tracker. I get a lot of questions about the fluid transition in the video. Here's the whole story. Initially, Claude built the grid with SwiftUI. It was quick and easy, and looked good! But the transition to the day view was a boring navigation push/pop. No fun. I wanted something custom. I asked Claude to make it a fluid transition that remaps the food tiles from their source to destination positions. All hell broke loose. Claude tried a bunch of horrible things. Initially it used matched geometry effects, which worked OK but didn't lend themselves well to gesture-driven animations. So it resorted to SwiftUI preference keys + geometry readers to figure out the source and destination positions and calculate the interpolated position based on gesture progress, coordinating across grid and day views. But this meant it had to write a custom layout because it couldn't reposition tiles inside the native SwiftUI grid. And it had to do an awkward handoff between views, which always created ugly pops or jumps. And don't get me started on trying to put it on a bouncy spring, that only made the math 10x buggier. Fortunately, Claude Fable was smart enough to see that this was becoming a disaster (and discover most of the issues itself, in the simulator), so it pivoted away from SwiftUI. Opus might not be so wise, so you'll have to pay attention and intervene. Ultimately, it rewrote it in plain UIKit and everything turned out great. After that, we moved from 2D images to 3D assets, which introduced a new set of performance challenges and yet another rewrite to a single Metal layer, which is what you see below. I can write more about the 2D-to-3D saga if anyone's interested. If I were to do it again, I'd just say "Don't use SwiftUI" from the very first prompt, and save a few hours of headaches. SwiftUI can be amazing for a human iterating directly in code. But agents don't benefit from any of its advantages. Plus, agents have seen decades of UIKit training data, so they're great at writing it, and it's far more flexible. Here's hoping we see more agent-friendly iterations of SwiftUI in the future. Till then, I'm probably going to avoid it.

For the past few weeks I’ve been teaching 50+ kids how to create their own games with AI. The results have been incredible 🤯 I started with my 5 y/o nephew because I was worried about him spending hours doomscrolling and consuming brainrot content. He built his first game using v0, though I had to walk him through each step. Watching kids interact with these tools taught me so much about how they think, where they get stuck, and what keeps them motivated. The moment that really struck me came right after he finished that first game. Every time I saw him afterward, he’d run up and ask, “Did you bring your laptop so I can keep playing?”. For him, “playing” meant creating. That kind of excitement is organic pull. Don’t get me wrong, I love v0 and Lovable. They’re insanely powerful. Their UIs just aren’t designed for kids, and that’s totally fine. Kids still need guidance, structure, and a bit of tutoring to turn ideas into something playable. I’m seeing tech leaders push in this direction too, and I think there’s a real opportunity here (Matias Woloski Thomas Wolf). Kids are the future, and I don’t want to live in a world where they spend precious time consuming instead of creating. That’s why I love tools like v0, Lovable, wabi , Cursor . They’re empowering more people to become creators. I want that same feeling for kids. What Guillermo is saying is real. Kids need to be AI-literate from the outset. It honestly makes me sad to think about my nephew growing up and falling behind on AI and everything happening around him because he’s stuck in Roblox or TikTok. That’s why I built Rabbit 🐰 for him. It started as a simple prototype, but somehow I ended up talking with 200+ parents and kids, tech leaders, investors, and people I never imagined meeting around the world. Rabbit now has 100+ people on the waitlist, and 10 kids are using it two to three times per week on average to create their own games 🫡 I’m not sure yet if this will become my full-time project, but I deeply care about it. If you’re building in this space, I’d love to connect and share ideas. And if you’re a parent interested in Rabbit, I’d love your feedback. Sharing a short video of kids using Rabbit below:

How 2 psyop yourself to success 🍸🥂 Visualization > + unmatchable lvls of desire (for a specific goal other than money) >> get addicted to work. [ and most importantly DREAM big, DREAM about it, think about it, work for it, and do it every single day, while your sleeping think about it, when you eat, do it, when your walking do it, when your working think about it] In lab studies I’ve compiled tons of data for behavior in hopes of using it for marketing purposes However, it also if curated shows you the triggers people react to The mindset changes that curate and sway them to do more of x (in this case work and create insane drive to achieving a goal or YOUR goals) Remember, every stimuli, every reaction curates your mind. When you come in contact with whatever it may be it sways your future behavior & current attitude/ psychological state So at all times if you want it bad enough you should try to curate your environment (special music that gets you in the mood or NO music, depends on the person bc music distracts you thus means you work less OR if you’re brain storming then it helps) Take out all negative energy, comments, or bs that distracts you and breaks your momentum because one it breaks from the smallest thing then that snowballs and has a negative effect going forward Another thing that I personally like to do is read and put myself into those shoes. For me it’s business and mindset related books and nothing compares to John D. Rockefeller’s mindset, work ethic and GRIT, his absolute desire for SUCCESS : I like his 38 letters to his son, John D the founding fathers of the rockefellers, and a study in power. And most importantly you need to just want it bad enough. Lose sleep for it, not because you want it but because you want it so bad that you’re working nonstop to get to it. This is how Rockefeller succeeded How Elon musk succeeded James Dyson Andrew Carnegie And most importantly how Peter kell succeeded All these billionaires and killers got hyper successful because of their drive and mindsets. It’s so important. If you believe something so strongly it’s revisited your mind to making it reality. Ex. Study DOI: 2003.11.018 > strongly visualizing exceedingly finger abductors boosted muscle strength by 35% Another study showed that basketball players who visualized making free throws showed significant improvement over others. And so on and so on. We as marketers have practiced this forever. We know when we tell a emotional story it changes the viewers mind, and we can lead that into a sale at a much higher conversion rate To get a brutal mindset focused on a dream you have that you truly want with your entire being is the result of the same hormones and neuro pathways after they have been curated and triggered by specific stimuli like in a VSL or ad You need to build your mind, you need to build a dream and want it, give yourself inspiration with books and ideas and positive energy. Build motivation and joy by watching others do it and building proof elements that it can really be done in your mind. Break the barriers and limits Movies are good for this, I like edits for this exact reason because yes it can lead you to doom scrolling but also it can be so so valuable in making you see that goal, want it even more and go for it. I personally really like war dogs, lord of war, limitless, and probably a lot more I’m forgetting. But you get the idea. Your success is in your hands alone, if you believe it fully and truly with a pure heart, then it will happen. Good luck🥂 P.s. * I will drop data, sauce, and more info about this and the methods & stimuli I talked about in this thread continuously so bookmark and come back to check them out.

Dear Andrej Karpathy, Update on this. Earlier this month The Innovation Game (𝔦, 𝔦) announced a new SOTA routing algorithm had been collaboratively developed and submitted to The Innovation Game. The algorithm demonstrated the largest single perfomance jump in the modern history of the field on standard academic benchmarks: This success is a powerful proof of concept. I believe the wider implications will also interest you. As you know, the "Source" in AI is algorithms and data. These algorithms are typically for "hard to solve but easy to verify" problems. Remarkably, this allows the creation of a market for pricing improvements to these algorithms (roughly, the market is created by "racing" the algorithms, to see which can produce proof-of-work fastest). Availability of a market mechanism means open development of the algorithms can be funded by capturing a portion of the value they generate, and allocating it back to algorithm developers. The allocation is efficient, naturally integrating information (such as hardware availability) through revealed preferences. Importantly, market allocation is also "impersonal", which mitigates the risk to community cohesion that has historically afflicted Open Source projects offering monetary reward. Note: That a market for pricing code could extend Open Source to areas requiring monetary reward was (as far as I know) first suggested by Eric Raymond in 1999 Eric S. Raymond : Conclusion: The structure of Open Source AI means it can operate commercially. For example, value captured via Open Source "dual licensing", with allocation of the value by a market generated by proof-of-work. I'd love to hear your thoughts on this. Please see for more detail.
