Who needs AGI with Insta-Carmack
When I was writing Unreal Engine 1, my time was divided as follows: - Around 30% went to seriously deep coding on hard problems: assembly language texture mappers, C++ BSP trees, data persistence, object oriented systems design, and networking. - Around 70% was just typing and refactoring large bodies of code needed for a complete engine feature set. This was not hard, and while I was doing it my mind was mostly on the deeper coding topics, thinking and planning for what's next. It didn't feel much different from vibe coding today, except that it was just me typing code on an IBM Model M keyboard rather than prompting it and reviewing the results. So, it has always seemed perfectly logical that we would rely on AI for that 70%, once the AI could do it with a similar quality standard as we could, which has never been perfection. It came as no surprise that, after a few years of AI model evolution, it was able to take the reigns on that 70% and free up programmers' time for more valuable tasks. What's more of a surprise is the emergence of AI as a sort of insta-Carmack able to solve hard technical problems quite cleverly and often cleanly, and that it's able to reason about and work in complex 3D scenes both by operating the tools and by directly understanding the raw data files. I abandoned assembly language in 1998 when out-of-order CPUs made much simpler C/C++ code faster, and never I missed it. If prompting through architectural documents, concept art, and design plans can transcend typing code and tweaking vertices, that will enable developers to spend their time on higher-level, higher value technical and creative tasks. What matters is the end product, whether it's a game or an engine. Anything developers can do to try out more ideas and make better software and games faster is a win for everyone.

San Antonio might be one of the most underrated cities in America. In town to call UTSA vs. South Florida tonight on ESPN & been blown away. Heard these roadrunner fans are next level What an awesome city. The people, the food, the atmosphere…just incredibly impressed!

The computer revolution wiped out 2.8 million clerical jobs: typists, data entry keyers, file clerks, secretaries. It also created nearly 4 million jobs in computer occupations that barely existed in 1990. My @nytopinion Chart: nytimes.com/2026/10/02/opini…

Predictions are difficult, even for experts.
Don't get sucked in by the stats, folks. Derrick Henry is not an elite RB prospect.

You can have a persistent dedicated VM with oversubscription and live migration when resource utilization actually causes contention. This is a trivial workload management issue for modern operators. Ex. for inactive RAM -> disk (this is just swap, we've had this tech for decades).
Replying to @_clarktang
meta promised each user a persistent dedicated VM that can work 24/7 in the background, so CPU can be heavily shared but reserved RAM and disk still scale with users (if they keep that design)

JEV actually doesn't even run deterministically Exact same prompts give you different probabilities when you run it multiple times The ORDER of the choices DRASTICALLY changes the output probs I am more and more confused by the their "no-hallucination" claim
Guys it’s a misconception that Jev can’t hallucinate It’s a non-generative LM ie it models probabilities of things given language as context The guarantee is the type-safety, and that answers are deterministic - ie no stochastic sampling. The deterministic answers can still be confidently wrong! It can still hallucinate if the training data on the topic was under cooked

TBC would be excited and honored to build this massive infrastructure project. Because Loop/Hyperloop is express (i.e. no intermediate stops), one could travel from an Austin parking lot to a favorite San Antonio restaurant in ~30 min. As long as they both have Loop stations!
Replying to @elonmusk
Boring Company is working on a simple, precursor Hyperloop tunnel between Austin and San Antonio (>200 mph). Due to traffic congestion, that journey can currently take up to 2.5 hours. @BoringCompany can reduce that to a consistent <30 mins.

The complete Jev Report: docs.google.com/document/d/1… My AI reads everyone in AI community here on X to build these. Unless you are using my lists, you can't do this. And even then, my database has four million posts in it so I have more data than you do to feed my agent.

I'm hosting a hardware happy hour in Austin next Thursday — DM me (or reply) for the Partiful. Just did this same event in Hawthorne, and took over a local bar with 81 hardware engineers/operators. Attendees will once again receive free: ‣ food ‣ drink ‣ camaraderie

it's been < 36 hours we've jev-ed 140k off the waitlist (our platform team trying hard to get EVERYONE off ASAP) I've been told we're 9th biggest launch video of the year (and in very good company) SO many cool demos! evals! ideas! and still the most important number is going to be how much true automation y'all deploy!

Yesterday I was in Austin, TX to announce the Airbnb Housing Accelerator, a $250 million commitment to help get more homes built. Airbnb started because of a housing problem. My roommate and I couldn’t afford our San Francisco rent, so we rented out airbeds in our apartment. Today, housing is unaffordable for millions of people around the world. If you step back and ask why housing has become so expensive, the biggest problem is pretty simple: we don’t build enough of it. America is short more than five million homes, more than all the housing in New York City and Los Angeles combined. We build fewer homes today than we did in 1950, even though the population has doubled. Airbnb has been part of the housing debate, and we understand why communities have concerns. Dedicated Airbnb listings are a small share of the housing supply—about 0.5% here in Austin and 0.3% across the U.S. Restricting short-term rentals is an understandable response, but the evidence shows it doesn’t address the underlying problem. New York City effectively banned Airbnb, and rents have risen about 30% since then. Austin took a different approach and passed reforms that made it easier to build more housing. Rents there are down 18%. Every city is different, but Austin is a clear success story. We believe building more homes is essential to making housing more affordable. So we asked ourselves: what can Airbnb can do to help? We found a few places where we can. Today, around 750,000 homes in the U.S. are ready to break ground, but are stuck because they can’t get the final piece of financing. That’s where we can help. We’re doing four things: 1. Putting $250 million behind housing projects that unlock $5 billion in development. 2. Supporting local housing advocates working to modernize zoning, speed up permitting, simplify building codes and reduce unnecessary costs. 3. Creating a $5 million Housing Innovation Prize for technologies that can make homes faster and cheaper to build. 4. Launching the Airbnb City Index to make it easier to see which cities are building housing, becoming more affordable and adopting policies that work. Our first project is in Austin. We’re investing $6.4 million to help build 201 affordable apartments in St. John, a neighborhood where the land has sat empty for nearly 20 years. The community fought to turn this lot into affordable housing and won. But construction stalled for nearly five years because the developer was a few million dollars short. Airbnb came and played a small part to unlock this project. None of these Austin apartments will ever be on Airbnb. Short-term rentals aren’t permitted. We’re investing anyway, because the goal is simple: help build more housing. We’re starting in the U.S. because it’s the market we know best. I want to prove this works here before taking it further. But housing affordability is a global problem, and I hope we can eventually take what we learn here and apply it globally. This is new for us. We’ll get some things wrong. And $250 million won’t close a five-million-home gap on its own. I know there will be skepticism about this, and that's okay. Airbnb only works if communities trust us and feel good about our presence in them. We can’t ask people for that trust. We have to earn it. The best way to do that is to help solve problems in the communities where we operate. That’s what the Housing Accelerator is about. Brian

Interesting "Made with AI" tag on the photo from my prior post. I did clean up the lighting with AI, but that's really my wall. Wonder if this selfie that I did not edit also gets flagged and how the flagging of AI image impacts reach?
Getting ready to watch @FIBA Women's final and in @DAZN saw this @spurs announcement. This Spurs fan will not miss anything about the FanDuel Sports (formerly Bally or Fox Sports Southwest) experience at all. Thank you Spurs for getting a modern era media partner.

China published the most uncomfortable paper on vibe coding. ETH Zurich tested 100 developers in a controlled, commercial-grade vibe coding environment to see who actually succeeds. The findings are brutal. The researchers tracked computer science achievement, written communication skills, and general cognitive reasoning. They wanted to see what actually predicts vibe coding proficiency when you never touch a line of source code yourself. Two major predictors emerged. Written communication proficiency mattered. The ability to structure thoughts and articulate intent unambiguously in text directly impacts what the AI builds. But that wasn't even the main takeaway. Computer science achievement was a massive, dominant predictor of success. Even when researchers controlled for general intelligence and reasoning skills, CS background still heavily dictated who built working software and who completely crashed. In fact, CS knowledge contributed roughly twice the unique predictive variance of writing skills alone. Why? Because vibe coding isn't about writing code. It’s about debugging logic. When an AI agent builds a complex application and quietly breaks an edge case under the hood, a non-technical user looks at the glowing UI and assumes it works. They don't know what questions to ask. They don't know what logic to challenge. They lack the mental models to recognize architectural catastrophe. You can prompt your way past syntax. You cannot prompt your way past a fundamental lack of engineering intuition. The hype told us that learning to code is dead because language is all you need. The data just proved the opposite. To truly master the vibe, you still need to understand how the machine thinks.

Moved /home to btrfs with dynamic compression, cut my space usage in half on this new box. This feels like it should have been easier to setup than it was. Would a longer post explaining the technical step-by-step be useful to folks? Reasons I did it: 1. Taming the WSL VHDX Monster 2. /home Data Profile is Highly Compressible 3. Extended Laptop SSD Lifespan 4. Trade Abundant CPU for Bottlenecked I/O 5. Bonus: Copy-on-Write and Instant Snapshots Anyone else have some fun WSL performance or cool config setups to share?
