It's not my data. The source is Cluvio, which is linked to in the article. I'd link to it in this tweet, but ironically, that would kill engagement. And I know that traffic is hard to count. Especially for a private company. But if you have more accurate data, then publish it.

Our eGPUs don't just support USB4, they also support USB2 and USB3. Here's USB3 at 741 MB/s, super useful for adding GPU power to a cell phone or single board computer. The maker of the ASM2464PD bridge chip doesn't even know this is possible.

Yesterday SpaceX launched 29 more Starlink satellites from Florida. Nobody cared. Routine. Another Tuesday. Here is what actually happened. Satellite number 10,074 entered an orbit where 300,000 autonomous collision-avoidance maneuvers were executed last year alone. Not by humans. By onboard machine learning that screens conjunction data from 30 million object-transit observations per day, computes probability in real time, and fires ion thrusters if risk exceeds one in a million. The industry standard is one in ten thousand. SpaceX set its threshold 1,000 times stricter and then automated the entire thing. Three hundred thousand maneuvers. That is 820 per day. Forty per satellite per year. Every single one decided and executed by AI faster than a ground controller could open the alert email. This is Tesla Full Self-Driving logic running in vacuum at 7.8 kilometers per second. SpaceX did not stop there. In January they launched Stargaze, a space situational awareness network built on the star trackers already aboard every Starlink satellite. Thirty million observations daily, conjunction screening delivered in minutes instead of hours, and they gave the data away for free to every operator on Earth. They just made themselves the air traffic control system for low-Earth orbit and charged nothing because the real product is not the data. The real product is the standard. Now connect this to last week. Terafab breaks ground in Austin. One terawatt per year of AI compute. Eighty percent allocated to space. D3 chips designed to run hotter in vacuum where radiative cooling is free. Satellites with 100-kilowatt solar arrays scaling to megawatt. Optimus robots replicating from raw materials. The Dyson Swarm bootstrap. Every analyst covering Terafab is modeling chip yields, capital costs, and process nodes. Not one of them is asking the question that determines whether any of it works: how do you manage ten thousand satellites without a single collision, and then scale that to ten million, and then to five billion? The answer already exists. It launched its 300,000th maneuver months ago. It processes 30 million observations every 24 hours. It operates at a collision-probability threshold three orders of magnitude beyond what any government or competitor has achieved. And it improves with every satellite added because more nodes means more eyes means better models means safer density. This is the orbital operating system for a Kardashev II civilization and it is already running. The Hormuz crisis proved that terrestrial supply chains are molecule-dependent and fragile. The Terafab announcement proved that Musk intends to move compute off-planet. But neither of those matter if the orbital environment becomes a debris field. The collision-avoidance AI is the gate. Without it, every satellite launched is a lottery ticket for Kessler syndrome. With it, density becomes self-reinforcing instead of self-destroying. Nobody is covering this because it is not a product announcement. It is not a keynote. It is infrastructure so foundational that it has become invisible, the way TCP/IP became invisible the moment the internet worked. SpaceX did not just build a satellite constellation. They built the nervous system of orbital civilization and trained it on 300,000 real-world decisions before anyone realized what they were looking at. The rockets are visible. The chips are headline news. The AI keeping ten thousand objects from destroying each other in silence at eight kilometers per second is the actual breakthrough. And yesterday they added 29 more nodes to the network. Routine.

We’ll receive love after the AI4 model is complete for robotaxi and the model can be distilled for the AI3 hardware. Makes no sense to try and build and train two distinctly different models for different hardware at the same time; too much wasted time and resources, it’s coming in due time.

Tesla’s forthcoming AI5 uses a half-reticle design, which is crucial for yield. A reticle defines the imaging area of a lithography machine, fitting two chips per shot effectively doubles yield. This means the Tesla chip design team had to carefully manage die features, for instance dropping the older ISP (and classic GPU) to make room for more AI cores. By contrast, NVIDIA’s Blackwell fills nearly a full reticle, making it a single-reticle design. If Tesla hits its compute and efficiency targets with AI5 in this half-reticle format, it’s almost like cutting fab requirements in half. And this has a big impact on Terafab, especially if it carries forward for AI6, AI7, etc.

Terafab may be the most essential vertical integration Tesla has ever undertaken— and it is truly non-optional. It will take years to build and will test even Elon’s speedrunning abilities to the limit, but that won’t stop him from trying. The breakthrough likely lies in overhauling the overall facility’s cleanroom model. By moving wafers in sealed pods with localized micro-environments, the fab no longer needs a monolithic ultra-clean space. Elon’s line about “eating cheeseburgers and smoking cigars” on the fab floor isn’t silly, it’s the practical reality of a radically simpler, cheaper, faster approach that could finally change the economics of chipmaking. This is all forced by the brutal “pinch” in chip supply. Tesla must produce on the order of 100–200 billion AI chips per year just to saturate its roadmap. That volume powers: FSD cars & Robotaxis (tens of millions of vehicles needing AI5 inference for near-perfect autonomy), Physical Optimus (scaling from thousands today to millions per year, each requiring AI5/AI6-level compute), Digital Optimus (the new xAI-Tesla software agents for digital/office automation, running massive inference clusters), Space-based data centers (AI7/Dojo3 orbital compute for GW-scale training and inference beyond Earth limits). AI5 delivers the ~10× leap for vehicles and early robots; AI6 shifts focus to Optimus + terrestrial DCs; AI7 goes orbital. No external foundry (TSMC, Samsung, etc.) can deliver that scale or timeline— hence the Terafab launch. Without it, the entire robotics + autonomy future hits a brick wall. Terafab isn’t optional; it’s the only way forward.

I went to the exact same location of the Cybertruck accident shown in the Fox News video. This is the US-69/59 Eastex Freeway northbound HOV lane at the Y-split near the Eastex Park & Ride exit (approaching from downtown Houston toward Humble). In the Fox News video, the vehicle failed to follow the right curve, going straight into the barrier. Well, I tested it twice today with Tesla FSD engaged the entire time with zero human intervention. And unless you think I am a hologram speaking to you from another dimension now, it worked out really well. Here is the video of me taking the exact same curve twice, with Tesla FSD v14.2.2.5.

If you can get the video from a camera set up by the owner, why not request they post the footage recorded by Tesla dashcam that puts the guesswork to bed? It’ll show the status of everything going on with the drive (steering wheel, pedals, turn signal,etc) including if FSD was engaged.

Senator Chris Murphy of Connecticut... and you have to hear about this guy because it's one of the most incredible, most brazen, most dishonest examples of hypocrisy you'll ever see in American politics. Maybe ever. And there's a lot of competition, believe me. Back in 2014, Murphy is on the Senate floor, he's giving speeches, he's writing resolutions, and he's telling every Republican in Washington... don't you dare undermine these Iran negotiations. Don't do it. He said if Congress shows it doesn't take the talks seriously, it'll destroy our credibility with allies, scare off our negotiating partners, give Russia and China an excuse to walk, and leave us with nothing but a military option. His words. Not anyone else's. His words. And by the way, Trump rebuilt the military, made it the strongest, the most powerful, the most technologically advanced fighting force the world has ever seen... nobody's even close... so the military option isn't quite the disaster it would've been under the previous administration, but that's a separate story. So what happens? Trump gets back into office, and he starts serious indirect talks with Iran. April 2025. Oman-mediated. Very tough, very sophisticated negotiations. Steve Witkoff, incredible guy, working the back channels. Trump gave them a real deadline... sixty days... because he doesn't do endless process. He does deals. Zero enrichment, ship out the uranium, dismantle the key sites, open the doors to inspectors. Clear demands. Generous terms, frankly, very generous, because he didn't have to offer them anything. He could've just hit them. But Trump wanted to give diplomacy a chance because that's what a strong leader does. And what does Murphy do? The same Chris Murphy who said you must not undermine negotiations while they're happening? He goes on television. He goes to Iran International, which the Iranians are watching, and he calls Trump a liar. Says he has no idea what Trump is trying to achieve. Says most of what Trump says isn't real. He pushes war powers resolutions to tie the President's hands. He's out there broadcasting American division to the entire world... to Iran, to our allies, to everybody... while the United States is sitting at the table trying to close a deal that could've avoided all of this. All of it. And it gets worse. Murphy secretly met with Iran's foreign minister, Javad Zarif, back in 2020. Secretly. Behind everyone's back. During Trump's first term. So he'll freelance with the Mullahs, but he won't support his own country's negotiating position when it matters. Think about that. Iran watched all of this. They watched Murphy trash America's leverage in real time. They saw the division. They stalled. They rejected every core demand. Zero enrichment? No. Ship out the uranium? No. Dismantle the facilities? Absolutely not. And the talks collapsed. They collapsed because Iran believed... correctly, unfortunately... that they didn't have to make a deal because half of Washington was working against the other half. And Murphy was leading the charge. So the only card left was the military card. The very thing Murphy warned about in 2014. The very thing he said would happen if politicians undermined negotiations. He predicted the mess. Then he spent a year engineering the mess. Then the military option becomes necessary, and now he's on NPR calling the war "incoherent." Now he's calling Trump senile. Now he wants to block all Senate business and defund the operation. The man who helped make the war inevitable is now complaining about the war. Incredible. And by the way... this is the same guy they're floating for 2028. That's their big idea. A senator from Connecticut who sabotaged his own country's diplomacy, sided with Iran's talking points, and now wants to be President. Good luck with that, Chris. Good luck. You have to ask the question. At what point does undermining your own country's foreign policy in the middle of the most sensitive, most high-stakes, most consequential negotiations in decades... at what point does that stop being opposition and start being something else? Because the people of Connecticut deserve better, the people of this country deserve better, and our incredible warriors now in harm’s way... including the 13 who lost their lives because diplomacy failed... they sure as hell deserve better than Chris Murphy.

No, it’s just a side hustle for a product that was already developed and sold. Tesla investors recommended Inference as a service (IAAS), the Tesla team thought about, built the toolset to deliver the goods and partnered with xAI that has the training compute. Turns out the vehicles already had everything needed; power, inference compute, cooling and sits idle 80% of the day. Now it will have a side hustle.
