🚀 Yesterday I had the chance to share a deep dive into Andromeda, the latest upgrade on @MultiversX, during a live session on @GM_Web3. What followed was a flood of questions and for good reason. This isn’t just another performance tweak. Andromeda quietly rewrites the way blockchain networks can scale, finalize, and secure themselves. 🔹 In the past, MultiversX relied on layered safeguards: confirmation blocks, rotating validator groups, and proposer-based finalization. All of it worked but at a cost: latency, complexity, and bottlenecks. 🔹 Andromeda flips that model. Finality is instant. Every validator participates. Equivocation risks are neutralized. And cross-shard execution becomes twice as fast. 🧩 It opens new doors: → For builders, it simplifies logic and unlocks real-time apps. → For enterprises, it enables sovereign chains to scale securely. → For users, it makes transactions feel… seamless. And the most exciting part? Andromeda is only the beginning.

@esa @NASAArtemis @ESA_Hera @CopernicusEU The Service Module work is solid and necessary. What is still missing is a clear European path to significant surface infrastructure. Right now the contribution is real but limited in scope compared to the overall lunar ambition.

@elonmusk This is one of the features that actually changes daily workflows. The interesting test is how well it holds up on complex, real-world footage rather than short clean clips.

@karpathy The fact that it can spend two hours on something no human would ever finish is new. The next real leap will be when it can also reliably watch and correct the result.

We're starting to leave the territory where you'd test an LLM by e.g. "create an svg of pelican on a bicycle". As one idea to generalize it, I was interested what Opus 5 would do if I gave it the first paragraph of the Lord of the Rings, a 1M token budget (~$10) and asked for three js render of it. Opus went off for ~2 hours and wrote 5500 lines of code that (procedurally) rendered the story. It's kind of janky but fun. But it's a bit mindboggling that the LLM has to place and orchestrate various polygon assets in (x,y,z) coordinates and write code that animates it all, and that it even does anything at all. I also like this kind of examples because no one in their right mind would ever spend the time to write something this custom but LLMs have all the stamina and patience in the world, so it's an example where we go from "no one would ever do this" to "sure, why not, it's ~free". There might be a lot more. But I'm excited about creating hyper custom worlds that you can imagine dropping players into, e.g. here to participate in the LoTR story as a spectator NPC, or one of the characters, or etc. Something like an ephemeral GTA of X on demand. Last thought is that the domain of worlds/games exposes a weakness in LLMs: they can't easily audit their work because they aren't able to efficiently and natively perceive videos or play games within them. Here, Opus 5 had to very slowly and painstakingly take screenshots at different points, and it messed up a few times and created a bunch of jank. An example of raw capability (multimodal, gameplay) that I think is still quite lacking.

@SciGuySpace The design still looks like it belongs in a science-fiction film. Clean single-stage form, vertical takeoff and landing, almost no visual clutter. Thirty years later most operational rockets still look more conservative than this prototype.

@elonmusk A Moon base will need far more than habitats and power. Local networking, surface compute, and a reliable link back to Earth (Starlink-style or otherwise) will be foundational. Is there already a concrete plan for the lunar network and data infrastructure in @SpaceX backlog?

Many have asked how this photo was made. This is my explanation. The ISS rotates about its pitch axis as it orbits Earth at 17,000mph to keep its nadir view constant. Because of this long exposure photography turns stars into arced lines. Sidereal clock drives on Earth match the planet's rotation to see stars clearly. I knew one designed for space could do this too. So a camera mount was custom built at @RITtigers to rotate once every 90 minutes using a 60 to 90 toothed gear system, cancelling out the orbital motion of ISS and allowing the capture of distant stars as fixed points! In essence, it is a a rotational coil spring powered analog star tracker. It was machined out of aluminum and is entirely mechanical to bypass NASA's strict electrical requirements for cargo. We had to get creative! After Expedition 72 it was safely returned to Earth and is to be displayed at RIT. Which I am pleased to say because a similar barn door tracker I made from spare parts on Expedition 6 for nighttime city photography was destroyed in an atmospheric trash disposal! Photography is an important part of sharing the journey to new frontiers for all people of Earth!

@elonmusk Checked this on a small SRE log-analysis benchmark I created. Not the absolute highest score, but extremely close while being far cheaper than the models that beat it. That combination is usually more useful in practice.

I understand the Moroccan historical perspective through the Marinids and Maghreb history. Memory matters. But picking the most favourable date is unworkable. By that logic Italy could claim half the Mediterranean on the basis of Rome, and China uses the same approach with Taiwan. Once you start, there is no logical end. Ceuta and Melilla in their current form were built under continuous Portuguese then Spanish rule. The people who live there are Spanish citizens and want to stay Spanish. Current population will beats competing maximalist maps.

@PhyByte @vonderleyen Ceuta and Melilla are, from the Moroccan perspective, a legacy of the history of Al-Andalus. And let's not forget that Morocco had a long-established civilization and was a major empire when what is now Spain was largely represented by the Kingdom of Castile.

The images coming from Ceuta are unacceptable. We cannot allow anyone to come to our Union without abiding by our rules. Dangerous crossings must stop immediately. Smuggling networks must be dismantled. And returns must be swift, as our rules allow. I tasked two Commissioners to support to control the situation. @magnusbrunner is already working closely with Spain and is ready to travel to critical points. He will work on additional operational support to Spain, including through Frontex. @dubravkasuica is in contact with her Moroccan counterpart. I am confident that our close partnership with Morocco will help deliver concrete results.

@vonderleyen @magnusbrunner @dubravkasuica If returns can be organised this efficiently once the cameras are on, the more interesting question is why the coordinated push was allowed to happen at all. The capacity was clearly there. The will appears selective.

Ursula von der Leyen@vonderleyen·
I held a conference call with Commissioners @magnusbrunner and @dubravkasuica for an update on the situation in Ceuta. The good news is that the vast majority of those who arrived illegally have returned to Morocco, due to the effective work of Spanish and Moroccan law enforcement. Not a single person reached mainland Spain or the rest of the EU. This shows why the control of our European borders matters. We have a strong system in place. But it needs to be further strengthened. We must remain vigilant at every critical entry point and maintain close coordination between all authorities. At the same time, we need a lessons learned process to improve our European resilience. The Commission has offered support to Spain from the first moment. I received letters from several leaders and I welcome the call for an extraordinary videoconference to take stock of what has happened. Fighting illegal migration requires solidarity and a united European response.

Ceuta and Melilla were never Moroccan cities in any meaningful sense. They were developed over centuries under Portuguese and then Spanish administration. The infrastructure, ports and urban fabric that exist today were built by Spain. Wanting the finished product after someone else built it is a recurring pattern, not a new argument.

@PhyByte @vonderleyen Ceuta and Melilla are two Moroccan cities under Spanish occupation. If you truly believe in democracy, then leave our land. We entered our own territory—we did not come to your country or enter your land.

The current situation at the borders is a symptom. The underlying process is a civilisational transition driven by two forces: sustained low fertility in Europe and continuous high immigration from higher-fertility societies. When a population stops replacing itself while remaining open to large external inflows, the demographic and cultural baseline shifts within a few generations. Most political debate still treats this as a short-term management problem. It is not.

Le immagini arrivate da Ceuta hanno dimostrato ancora una volta quanto sia urgente una risposta europea all’immigrazione clandestina. Per questo l’Italia ha promosso, insieme alla Danimarca, una lettera sottoscritta da 22 Stati membri dell’Unione europea, che chiede un’azione comune per rafforzare le frontiere esterne, contrastare l’immigrazione irregolare, combattere i trafficanti di esseri umani, rendere più efficaci i rimpatri ed eliminare ogni fattore che possa incentivare nuovi ingressi illegali. È un segnale importante: la linea che l’Italia sostiene da tempo è oggi condivisa da un numero sempre maggiore di Nazioni europee. La difesa delle frontiere esterne dell’Unione non è l’interesse di una singola Nazione. È una responsabilità comune dell’Europa.

@elonmusk Below-replacement fertility plus high immigration from lower-trust and lower-skill populations is not a stable equilibrium. It is a slow replacement of one population and its institutions by another.

@Nigel_Farage The numbers and the organisation matter more than the language. Once crossings become coordinated and repeated, it stops being a migration issue and becomes a sovereignty one.

@swyx Still using them too. On longer diagnostic or analysis runs the explicit goal acts as a useful checkpoint. Without it the agent tends to drift or restart reasoning from scratch when the context gets long.

among ai leaders i seem to be in the minority in that i am STILL actively using /loop and /goal.... ... and i think all of u guys who stopped using it are wrong - not wrong forever, just giving up on it too early in the g5.6/c5 era now you use it when: 1) you want the right mix of steerability and autonomy 2) you want open ended "loop that generates loops" type end state without deeply specifying path to get there heres an example of when having a goal on saved my ass in a very long action-reasonining turn

Yesterday I cohosted a dinner with @dexhorthy with a wonderful group of founders, to talk about agent loops and loop engineering. Some interesting insights: * Most of our group was *not* actively using /loop in Codex/Claude Code * You can build long-running autonomous agent loops through multi-agent handoffs, event triggers, or….just stacks of cron jobs (?) * Almost everyone believes that no one will be reviewing code in 1-2 years. * The more interesting question is whether we’d be reviewing *anything* in 1-2 years. * AI is still a bit of a skill issue. Humans are responsible for maximizing AI output and reducing slopification. * Will human intellect provide alpha as models get better, or will the playing field be leveled? Most people think it will be leveled a bit, but there is a need for humans to provide alignment, guardrails, judgment, creativity. * The minimum amount of context you need for AI could be just the codebase with some documentation. Any research/plan files are for one-off tasks and not meant to be maintained. Having a self-organizing wiki is nice but adds complexity. If you missed this one, we’ll be hosting more dinners like this on a regular cadence! If you have thoughts on what we should talk about, let us know :) (e.g. continual learning, RL envs, competitive differentiation vs. Anthropic, etc.)

@RocketLab @USSpaceForce Building realistic space test and training infrastructure is harder than most people think. You need high-fidelity simulation, real hardware-in-the-loop, and the ability to inject failures safely. The operational experience matters as much as the hardware.

The biggest shift is how models handle the absence of obvious error signals. On synthetic data they do reasonably well. On real logs they still over-index on keywords like ERROR or FAIL and systematically miss silent data loss or subtle state changes that never announce themselves. Red herrings (unrelated deploys, crons, network blips) also become much more damaging. Context window pressure is the other major difference. Complex multi-service incidents can explode the input size very quickly.
