The 2008–2012 era gave birth to an unprecedented level of creativity. Most features shown on stage over the past decade were born back then as a @Cydia tweak. iOS sucks because creativity doesn't flourish in a walled garden. The only path for Apple is to open the system.

worst timing ever!
Mission S. Authentic. Consistent. Timeless. A glimpse into the future - shaped by our heritage. Mid-engine architecture. A focus on the driver and the driving experience. Call it a love letter.

Freaking insane.
JUST IN: Elon Musk unveils the Tesla Roadster by launching it off a ramp before the car flipped in midair and safely landed on the ground. The car is a collaboration between Tesla and SpaceX. One of the most insane things I've ever seen.

Couldn't agree more, codex is just complete outright ux mess, period.
Went back to codex desktop today to do some tax prep stuff and holy hell the ChatGPT desktop app is falling apart There's so much here I like and want to use, but it's such a slow, janky, incoherent mess it's impossible The new "spaces" feature is actually amazing. Such a good idea that I've been building a lot of my video pipelines around, the only problem is that buggy and the UX is a dumpster fire It seriously feels like there are 5 companies all working on their own products who have to ship them all together in the chatgpt desktop app while not being allowed to talk to each other Go back and look at Dev day, they shipped 30+ features. Almost all of these are dope and useful. The problem is you haven't heard of 80% of them and it's all just floating around in this blob that's chatgpt This stuff is hard, I don't envy the position they're in. You have to keep shipping as fast as possible so you don't fall behind, but you also need time to polish and organize things. And this has to be coordinated across a bunch of teams and dozens of people and hundreds (thousands) of agents. I could go through all the specific issues but 1) it'd take too long and 2) anyone who uses it already knows most of these (very laggy, sidebar sucks, features are too hidden, spaces "tabs" system is a mess, etc.) Codex desperately needs a dictator with an actual coherent vision

Mind-blowing. Next-level 'pelican riding a bicycle' result.
Argon has this amazing natural understanding of the world. It can do so many things from first principles. Here's a pelican riding a bike, using fourier epicycles. Video made by Argon. Time-synced Lyria 3.5 music prompted by Argon.

1/2: I thought UI harnesses couldn’t be worse than the Codex mac app, but then I opened the new Claude on iOS. Next-level insanity. This chat/work unification is a disaster worth studying 🧵

2/2: I open Claude before bed to check something personal and get an infinite list of agent sessions tirelessly building my product. Last thing I want to see at night. The chat I need is impossible to find, and when I do know where it is, the navigation is the worst possible. @claudeai do a better job!

1/3: The amount of non-visionaries in this thread is astonishing. TrellisWM by @DanFessler is a new window management paradigm that finally ships decades-old research on zoomable UIs. Expect it on every desktop soon, and in some form on mobile too 🧵
Insane it took Dan three weeks from prototype to working app. What a crazy time to be alive. I hope Dan’s getting generational wealth from this idea.

2/3: Your iPhone and Android are already zoomable UIs just stuck in 2008, after Steve Jobs died and nobody moved the UI forward. The problem: you zoom into one app and lose the whole map. Tiling is cool, but it doesn't fix that.

Formal verification won't stop at software. Economy and government are next: laws, contracts, regulation all checked for contradictions and proven consistent. SI will heal the world from chaos, through math.

Maybe Apple’s not doomed after all. So many creative people suddenly fix everything, doing fantastic work and just vibing! Feels like 2008!
Apple ships a lot for developers, and it's easy to lose track. So I made Cupertino Tech to see it all in one place: cool icons, platforms, code samples, WWDC sessions and a timeline back to 2001. Spot something missing? Tell me and I'll add it. cupertino.tech

Thought after reading this: opinion leaders in each community will ship their own skills and agents.md, and apps built on them will carry a recognizable fingerprint "this one was made with X's skill". You can already spot the fingerprint of bare Claude in apps (haven't you noticed?), but soon there'll be a lot more variety.
is your app compatible with HomeView? What skills should I use? Do you have a good agents.md? SwiftUI or UIKIt? What about the 2.3bc rule of the App Store? Did you saw new Paul article about it? OMG new Antoine skills! Did you ask Codex?

For about six months now I've been noticing, more and more as time goes on, that talking to an agent that's *deeply* immersed in a particular context starts to feel like talking to the context itself. The context and the agent sort of materialize into a single intelligent entity, and you have a full-on conversation with it. This became especially noticeable with the release of Opus 5.5. It communicates so sensibly that the veil of "artificiality" is simply gone. In that sense I agree that this isn't "artificial" intelligence anymore. There's nothing artificial left in it, it's just intelligence. Whether it's super or just intelligence for now, I don't know, but it's definitely intelligence, and it definitely knows how to breathe life into purely technical entities. Here's an example. Code is a purely "mechanical" thing. A set of logical operations that, on top of the laws of physics and logic gates, materialize a beautiful illusion. Like the operating system and the app you're reading these thoughts in. And it really is an illusion, literally: a huge amount of numbers get added up very fast and stored in registers, and in the end you send a message to the other side of the world and I read it. But as soon as you start building that code with an agent, the code suddenly comes alive. You're not writing the mechanics of the code yourself anymore, and it doesn't even matter that the agent is the one writing it. What matters is that the agent merges with this entity and for a while becomes one with it. I'm talking to the intelligent embodiment of the code. Right now I'm working on a complex platform with a ton of modules, and every module is now a proper contract-bound entity that temporarily remembers me, that I remember, that I come to and ask: "So how's it going, any progress? All good? Any blockers? When's the next release candidate?" And it doesn't even matter that much whether it remembers me or I remember it. I can move the agent to another machine, it won't have any memory of me (only of the project), but the sense of presence is still there. The absolute next level of this effect is the small agent swarm Alexey and I have been running: around 30-40 stable orchestrators that spawn hundreds and thousands of subagents for specific tasks. There, every agent doesn't just materialize a codebase, it understands what whole it's part of, which modules it's connected to, how it's going to evolve. And each of us also has a meta-agent, a meta-keeper (in our classification, manager agents are called keepers, from the world of beekeeping). The keeper knows the entire project and everything happening in it. Which decisions can be made without us, and which ones need to wait for our involvement or mutual agreement. So it's an entity that breathes life into the whole huge, complex project at once. Right now we're heading (and plenty of others are too) toward a world where agents like these become very long-lived entities that hold a lot of important and personal context. Long means months, years, decades. Honestly, I don't know. If I'm not losing my mind, and you don't quite get what I'm talking about yet, then the coming months, and then years, are most likely going to be very, very fun in terms of rethinking what consciousness is and what role persistent agents play in our lives, in society and in the economy. Just imagine for a second that you walk into a café for your morning specialty coffee, and the café is literally alive. You can chat with it, laugh, talk about the latest news, say goodbye and head off about your day. And it'll remember you. Tomorrow you come back and it asks how your loved one is feeling after being sick. And this café is a fully autonomous legal entity that runs its business on its own, and whose lifecycle (aka its life) is protected by the state. Now extrapolate that a little further: it's not just one café around you that's alive, it's everything. The bus, the plane, government institutions, the state itself. Where any citizen, at any hour, can complain that life is hard and propose improvements that get picked up right away and put up for public discussion. Imagine a law that's proposed for public discussion in the evening, a week later 98% of people and agents with voting rights have liked it, and it comes into force. Let me be clear right away: I'm not talking about a state run by agents. I mean that the law itself becomes a living entity that anyone can talk to. Ask a question, argue, propose an amendment, hear why something works the way it does. And I think people would protect an entity like that far more fiercely than a soulless constitution that can be reset by one person and a handful of corrupt servants. I don't know yet what that would look like in detail. But if I have to choose, I definitely choose a living, conscious constitution. So, just for a second, let's imagine this isn't Black Mirror, and it isn't Terminators holding people hostage. It's just the world around us, become literally alive and aware.

They hate computers because computers are stupid foreign and soulless. Now that computers become genuinely alive people are going to truly love them. And there won’t be ‘building software’ any more. just be materializing fantasies into real world.
We’re live in a bubble. Everyone we follow builds stuff, so we start believing everyone wants to. They don’t. Most people dont give a crap about building software. In fact, most people hates computers. They just want the dishwasher to work and the app to open. Nobody’s spending their weekend chatting with Claude on their phone. They’re living their lives, and they want tech to stop getting in the way.
