John Carmack on what he admires about Elon Musk Programming legend John Carmack is asked about his relationship with Elon Musk, to which he replies: “In some ways we have a similar background. We’re almost exactly the same age, have backgrounds programming personal computers, and have even read similar books that have turned us into the people we are today.” John first met Elon when he was building Armadillo Aerospace. Elon visited Armadillo with his right-hand propulsion guy, and the three of them talked about rockets. “I think in many corners [Elon] does not get the respect he should for being a wealthy person who could just retire,” John says. “He went all-in, and he could’ve gone bust. There’s plenty of athletes or entertainers who had all the money in the world and blew it. [Elon] could’ve been the business case example of that with the things he was doing: space exploration, electrification of transportation, and Solar City type things. These are big, world-level things. And I have a great deal of admiration that he was willing to throw himself so completely into that.” John contrasts this with the way he approached his own aerospace company: “I was doing Armadillo Aerospace in this tightly-bounded way. It was ‘John’s crazy money’ at the time that had a finite limit on it. It was never going to impact me or my family if it completely failed, and I was still hedging my bets working at id Software at a time when [Elon] had been really all-in. I have a huge amount of respect for that.” It also irritates John when people call Elon “just a business guy”: “Elon was deeply involved in a lot of the [technical] decisions. Not all of them were perfect, but he cared very much about engine material selection and propellant selection. For years he’d be telling me to ‘Get off that hydrogen peroxide stuff. Liquid oxygen is the only proper oxidizer for this.’ And the times that I’ve gone through the factories with him, we talked about very detailed things like how this weld is made or how this subassembly goes together. He’s really in there a very detailed level . . . I worry a lot that he’s stretched too thin. He’s got the Boring Company and Neuralink and Twitter too whereas I know I have limits on how much I can pay attention to.” John continues: “I look back at my aerospace side of things, and I’m like, ‘I did not go all-in on that.’ I did not commit myself at a level that it would’ve taken to be successful there. And it’s a weird thing having a discussion with him. He’s the richest man in the world right now, but he operates on a level that is still very much in my wheelhouse on the technical side of things.” Video source: @lexfridman (2022)

🚨 STARLINK HITS 8.6 MILLION USERS: ELON’S SKY-NET IS OFFICIALLY ONLINE Starlink just crossed 8.6 million subscribers, turning Elon’s space-based internet experiment into a full-blown global ISP juggernaut. What started as a lifeline for remote areas is now delivering high-speed internet to dozens of countries, connecting war zones, deserts, mountains, and basically anyone with a dish and a clear view of the sky. No government involvement and no telecom monopoly. Just thousands of satellites, beaming WiFi from orbit like it’s sci-fi made real. And with 10,000+ satellites expected by 2026, this isn’t a network, it’s orbital dominance. Next step? Probably streaming Netflix from Mars. Source: @muskonomy, @Starlink

Javier Milei on Censorship in UK 🇬🇧 "Since the socialists came to power, they have been jailing people for posting on social media, and the journalists here would like that too, because they don't like that they have lost the monopoly of the microphone and the ability to use that tool to extort and smear, to defame without any cause. Social media makes them accountable, and they don't like it. Now the people are doing it organically because they realized many of them are criminals."

GROK-4 OUTPERFORMS TOP AI MODELS ON TRUTH SEEKING AND CAUTIOUS REASONING New research using Sparse Autoencoders shows a clear behavioral gap among frontier AI models when facing uncertainty. Instead of guessing, Grok-4 consistently pauses, clarifies assumptions, and seeks truth before answering. In ambiguity clarification tests, Grok-4 triggered this behavior roughly 70 percent of the time, far ahead of GPT-5, Claude Sonnet-4, DeepSeek-R1, and Gemini-2.5-Pro. The study flips interpretability on its head by using SAEs to analyze outputs themselves, treating latent features as thousands of soft labels for unstructured text. SAEs are a tool used to understand what AI models are actually thinking. Normally, big AI models have millions of internal signals firing at once, all tangled together. It’s powerful, but messy and hard to interpret. Across four analysis tasks, SAEs outperformed baseline methods and revealed model “personalities” directly from behavior. Grok’s edge appears tied to its design philosophy: prioritize truth seeking, surface uncertainty, and avoid confident nonsense. When reality is unclear, caution beats speed, and the data shows it.

Improving RAG with Forward and Backward Lookup This is a clever use of small and large language models. Traditional RAG systems compute similarity between the query and context chunks, retrieve the highest-scoring chunks, and then generate. But complex queries often lack sufficient signal to retrieve what's actually needed. That said, it could be useful if the RAG system could peek into potential future generations. The paper introduces FB-RAG (Forward-Backward RAG), a training-free framework that peeks into potential future generations to improve retrieval. A lightweight LLM generates multiple candidate answers with reasoning, and the chunks most relevant to those attempted answers get scored highest for retrieval. Even when the smaller model fails to answer correctly, its reasoning attempts contain enough relevant language to identify the right context chunks for a more powerful model. The approach works in three stages. Stage I uses an off-the-shelf retriever to narrow the context, optimizing for recall. Stage II runs a lightweight LLM (8B parameters) on that reduced context, samples multiple reasoning+answer outputs, and scores each original chunk by how well it matches any sampled output. Stage III feeds only the highest-scoring chunks to a powerful generator (70B parameters) for the final answer. The results are consistent across 9 datasets from LongBench and ∞Bench. On EN-QA, FB-RAG matches the leading baseline with over 48% latency reduction, or achieves 8% performance improvement with 10% latency reduction. The approach outperforms OP-RAG, Self-Route, and vanilla RAG across QA, summarization, and multiple choice tasks. Forward-looking alone outperforms combining forward and backward components. Setting the backward weight to zero consistently produces better results than averaging, indicating that once you have LLM-generated reasoning, the original query adds no useful signal. Even a 3B model for forward lookup shows visible improvements. The reasoning doesn't need to be correct. It just needs to contain relevant language that points toward the right chunks. Smaller models can systematically improve larger ones without fine-tuning or reinforcement learning. The lightweight forward pass filters context more precisely than query-based retrieval, reducing both noise and latency for the final generation step.

The next scaling frontier isn't bigger models. It's societies of models and tools. That's the big claim made in this concept paper. It actually points to something really important in the AI field. Let's take a look: (bookmark for later) Classical scaling laws relate performance to parameters, tokens, and compute. More of each, better loss. These laws have driven a decade of progress. But they describe a single-agent world: one model, static corpus, one prompt at a time. There is a clear misalignment with how real-world problems actually work. This new perspective paper argues that scaling must expand along three new axes: population, organization, and institution. Not just how many parameters, but how many agents, how they're connected, and what norms govern their interaction. Simply adding more agents doesn't monotonically improve performance. Early experiments in multi-agent debate show that naive agent swarms can degenerate into majority herding, where the first plausible-but-wrong answer locks in and gets reinforced through subsequent rounds. Groups of frontier models fail to integrate distributed information, displaying human-like collective failures. The paper proposes three interaction regimes for multi-agent systems: 1) Competition: debate, adversarial critique, self-play. 2) Collaboration: role specialization, division of labor, complementary expertise. 3) Coordination: orchestrated workflows, planner-worker hierarchies, reliable execution. Which regime fits which task matters. Competitive regimes suit focused reasoning problems with clear correctness criteria. Collaborative regimes fit an open-ended design where diverse skills are needed. Coordinated regimes handle long-horizon, safety-critical workflows. The architectural implications are significant. Effective multi-agent systems need cognitive diversity: agents with different priors, reasoning styles, and tool access. They need institutional memory: persistent artifacts that outlive individual sessions, analogous to lab notebooks and version control. They need communication topologies: not just broadcast or hub-and-spoke, but structured graphs that balance diversity and coherence. Training objectives must change, too. Current models optimize individual next-token prediction. Multi-agent systems need collective objectives: group accuracy, calibration, hypothesis diversity, and conflict resolution quality. The paper proposes "multi-agent pretraining" where debate, peer review, and negotiation become first-class optimization targets.

Elon Musk in 2019 on LiDAR: “They’re all going to dump LIDAR; that’s my prediction. I should point out that I don’t actually super hate LIDAR as much as it may sound. But at SpaceX, SpaceX Dragon uses LIDAR to navigate to the space station and dock. Not only that, SpaceX developed its own LIDAR from scratch to do that, and I spearheaded that effort personally. Because in that scenario, LIDAR makes sense. In cars, it’s freaking stupid. Once you solve Vision, it’s worthless.”

🚨🇬🇧 UK LEADS EUROPE IN RAPE RATES - SHOCKING STATS SPARK DEBATE ON IMMIGRATION, CRIME, AND CULTURE New data's out, and it's grim. The UK is sitting at the top of Europe's rape incidence chart with a staggering 109.06 cases per 100,000 people, far ahead of Sweden at 68.50 and France at 59.00. The figures come from Restore Britain's analysis of World Population Review data. The drop-off after the UK is steep. Norway stands at 41.50, Denmark at 32.50, and rates fall sharply from there. On raw numbers alone, the UK is an extreme outlier. This isn't just statistics - it's a political and cultural flashpoint. Many argue mass immigration policies and weak border controls have imported cultural conflicts and driven crime spikes. Others focus on failures inside the system itself: low conviction rates, collapsed trust in policing, and victim-blaming dynamics that discourage reporting. Comparing rape statistics across countries is notoriously messy. Definitions differ, counting methods vary, and reporting incentives are not uniform. Still, the UK's numbers are difficult to dismiss. High-profile cases, collapsing conviction rates, and growing public anger are pushing the issue into the center of national debate. Calls are mounting for tougher immigration controls, stronger cultural integration expectations, and major reforms in how sexual violence is investigated and prosecuted. Whatever the cause, the current trajectory is so obiously unsustainable. Source: Restore Britain, World Population Review

Elon Musk: The economic pie is not fixed, so work on adding to the economic pie, creating more than you consume "When we see people, including some very smart people, taking an attitude of doing things that seem morally questionable, it's often because they have, at a base axiomatic level, a zero-sum mindset. If you have a zero-sum mindset, then the only way to get ahead is by taking things from others. If the pie is fixed, then the only way to have more pie is to take someone else's pie. But this is false. Obviously, the pie has grown dramatically over time, the economic pie. So, in reality, there's a lot of pie. The pie is not fixed. So, it's much better to work on adding to the economic pie, creating more than you consume." Source: @MarioNawfal

This set a terrifying precedent for parents everywhere. A Canadian father, Robert Hoogland, was thrown in prison for trying to prevent his 14-year-old daughter from undergoing permanent medical transition. After schools socially transitioned her behind his back and courts authorized testosterone injections against his wishes, the state stripped him of his parental rights. When he refused to remain silent about the medical risks and the loss of his child, the government moved to silence him by force. https://t.co/3kK4Jotk6n Hoogland was sent to prison for "contempt of court" because he defied a gag order that forbade him from referring to his child as his "daughter" or using female pronouns. By treating his desperate plea to protect his child as a criminal act, the court signalled that the state, not the parent, owned the child. This is nothing less than the criminalization of parenthood in the face of state-sponsored gender ideology.

In this short ~1-minute clip from 2011, Elon Musk explains that Tesla will become a great American company—one that Americans will be genuinely proud of, just like iconic tech giants (Apple, google).

Wisdom teeth may be more valuable than we once thought Scientists have found that wisdom teeth contain dental pulp stem cells (DPSCs), a type of adult stem cell with notable regenerative potential. Because these cells originate from neural crest tissue, they show a higher-than-average ability to support nerve repair and differentiate into neuron-like cells under laboratory conditions. Researchers are actively studying DPSCs for their potential role in neuroregeneration, including applications related to spinal cord injury, stroke recovery, and neurodegenerative diseases such as Parkinson’s. In preclinical studies—primarily cell cultures and animal models—these cells have demonstrated the ability to promote neuronal growth, reduce inflammation, and support damaged nerve tissue. That said, this research is still experimental. There are currently no approved human treatments using wisdom tooth stem cells for neurological disorders, and significant clinical testing remains ahead. While stem cell banking of dental tissue exists, its future therapeutic value is promising but unproven. Bottom line: wisdom teeth aren’t medical gold—yet. But what was once considered medical waste is now an active area of regenerative medicine research, particularly in neuroscience. Sometimes progress starts in unexpected places… including the dentist’s chair. #StemCells #RegenerativeMedicine #Neuroscience #MedicalResearch #FutureOfHealthcare

TESLA FLIPS THE SWITCH ON A MEGAPACK GIANT IN CALIFORNIA Tesla has brought a serious heavyweight online in Kern County, California: a Megapack battery system paired with 500 megawatts of solar generation. That combination puts the project among the largest solar plus storage sites in the United States, and it is now fully operational. At full output, the site can supply enough electricity to cover the annual needs of roughly 467,000 homes. More importantly, it does so when the grid actually needs it most. Power generated during sunny daytime hours is stored and then released in the evening, when demand spikes and solar production drops. That shift alone helps prevent outages and reduces reliance on gas peaker plants. The emissions impact is just as significant. The project is expected to cut more than one million metric tons of carbon dioxide every year, while adding real stability to a grid that has struggled during heat waves and peak demand events. California has quietly become the proving ground for large-scale battery storage, and this site shows why. Energy storage is no longer theoretical or niche. It is operational, reliable, and scalable. Tesla’s Megapack footprint keeps expanding worldwide, and projects like this make the case clearly. Clean energy is not just about generation anymore. It is about control, timing, and resilience.
