New "superman" Four months later, Shanghai-based Matrix Robotics unveiled the Matrix-3--yet another anthropomorphic humanoid robot situated on the left side of the "Uncanny Valley." Unlike Boston Dynamics' Atlas, which is designed for industrial settings, the Matrix-3 is a general-purpose humanoid robot intended initially for service-oriented environments such as supermarkets, hotels, and office buildings. Standing 1.7 meters tall and weighing 65 kilograms, the adult-sized robot features a full-body covering of biomimetic fabric integrated with tactile sensors, as well as humanoid biomimetic muscles. It employs linear joints rather than the mainstream rotary joints. Matrix claims it is capable of pulling or pushing a load of 200 kg. Optimus makes extensive use of linear joints (linear actuators). It is equipped with dexterous hands offering 27 DOF and boasts a battery life of 4 hours. The robot is powered by a model named WAVE(like an E2E World Action Model) Matrix states that it has already established a manufacturing facility in Shanghai's Zhangjiang with an annual production capacity of 10,000 units. The company plans to deliver 1,000 units this year, with the first batch scheduled for delivery by the end of June. Pricing starts at $99,000. Notably, Matrix founder Zhang Haixing previously served as a leader at Tesla China's Design and Research Center, where he was deeply involved in the early-stage R&D and design of the Optimus robot. This company seems to be delivering on the future envisioned for Optimus.

Everything Elon said about Optimus at the All-In Summit today: • We’re finalizing the design of Optimus v3. That release is going to be a very remarkable robot. It will have manual dexterity comparable to a human, meaning a very complex hand, an AI mind that can navigate and comprehend reality, and will be made in very high volume. • Other robotics companies are missing those three very hard things. • I spend more mental cycles on Optimus than any other single thing. Solving real-world AI, all of the electrical-mechanical issues, the supply chain, and production challenges. • There is no supply chain for humanoid robots, so it has to be created from scratch, which requires a lot of vertical integration. None of the actuators in Optimus are available from an existing supply chain. • I think if successful, Optimus would be the biggest product ever. • The marginal cost of production, once we hit a million units per year, will probably be around $20,000. It depends on how much we spend on the AI chip in the robot, and we’ll need to achieve a lot of efficiencies in the actuators—26 actuators per arm (26 motors, gearboxes, and power electronics). The AI chip might cost $5,000 or $6,000, maybe more. At 1 million units a year, production cost will be $20,000, maybe $25,000. Price will be a function of demand. • Human hands have evolved to be incredibly sophisticated machines. Hands are a very first instrument. You can swing a baseball bat, thread a needle, play a piano or violin, and assemble a car. Hands are incredibly versatile instruments. Most of the muscles of the hands are actually in the forearm, and the hand is almost like a puppet. Human tendon evolution is incredibly good. The human hand has 27 or 28 degrees of freedom, depending on how you count it; it’s amazing. • In order to create a robot that can be a generalized humanoid, you must solve the “hands problem.” • Even though there are 10,000 to 20,000 electric motors out there, we couldn’t buy the actuators for any amount of money. We had to design every electric motor, gearbox, and controlling electronics from scratch, from first principles of physics. • Optimus is harder than developing any previous Tesla product, but not harder than Starship. • Right now, we’re struggling with the final design of the hardware, primarily the hand. The hands and forearm are the majority of the engineering difficulty of the entire robot. • If you want to do all the things that a human can do, it turns out you need a humanoid robot. If you want to do a subset, that’s much easier. Humans evolved to the shape and capability that we have for a good reason. There is value to having four fingers and a thumb; even the pinky is quite useful. Toes are much more of a question mark. • The AI5 inference chip will be 40 times better than AI4 by some measures. We know the limiting factors of the chip because the AI software and hardware teams work so closely. Effectively, the Tesla AI hardware and software teams are co-designing the chip. • The Softmax function on AI4 takes 40 steps in emulation mode, which will take only a few steps in AI5 natively. AI5 will easily handle mixed precision. • In terms of nominal raw compute, the AI5 inference chip has 8 times more compute, 9 times more memory, and 5 times more memory bandwidth compared to AI4. Because we’re addressing some core limitations and optimizations at the silicon level, we’re able to realize 40x improvements.

Aaron Siri sued the CDC with one simple demand: Show us the studies that allegedly prove vaccines do not cause autism. Their answer will shock you: “40 to 70% of parents who have a child with autism report that they believe vaccines cause their child’s autism.” “When you ask them what vaccines you think cause your child’s autism, they’ll say the vaccines given in the first six months of life.” “On behalf of ICANN … we sent a Freedom of Information Act request, FOIA request to the CDC.” “We said, your website says vaccines do not cause autism. Please give us the studies that show that Hep B vaccines given three times in the first six months of life do not cause autism.” “Please give us the studies that show that DTaP vaccine given three times in the first six months of life do not cause autism.” “Same thing for IPV vaccine, for PCV vaccine, and for HIV vaccine.” “Each one of those vaccines is given three times each in the first six months of life. 15 injections.” “They never gave us the studies.” “I sued them in the Southern District of New York.” “Days before the hearing, I get a list of 20 studies, finally, from the DOJ, because they represent the CDC.” “19 of them have nothing to do with the vaccines given in the first six months of life.” “They were all either MMR studies or studies of an ingredient that wasn’t in those vaccines.” “One of them was an Institute of Medicine [study] from 2012 that canvassed all the literature on whether DTaP vaccine does or does not cause autism.” “The Institute of Medicine … said, we can only find one study on DTaP and autism.” “And in fact it showed an association between [the] DTaP vaccine and autism.” “But the IOM threw it out because they said there’s no unvaccinated control in it.” “When their back was to the wall, they had nothing.” “There are no studies.” “They could not produce one that showed the vaccines given in the first six months of life do not cause autism.” “Here’s the thing they left out: there is one study out there regarding Hep B vaccines and autism.” “It’s from Gallagher and Goodman out of the University of Stony Brook.” “And it showed that kids that got Hep B vaccine versus those that did in the first month of life had three times the rate of autism.” Joe Rogan Aaron Siri

🚨BREAKING: CONSERVATIVE FIREBRAND SCOTT PRESLER TO STORM WA STATE TO PUSH FOR ELECTION INTEGRITY Scott Presler, the unstoppable force behind Donald J Trump's 2024 landslide victories in battleground states, just dropped a bombshell announcement that he is packing his bags and heading to Washington State to launch a signature blitz for Initiative Measure IL26-126, which would require proof of U.S. citizenship to register to vote and could lead to the cancellation of registrations for those unable to provide it, "Washington's been a playground for the radical left's voter fraud factory for too long," Presler stated in his announcement on X. "I'm coming to fight – and we're going to WIN!" The initiative, filed by the Washington State Republican Party in 2025, seeks to align state law with federal requirements but has drawn criticism from groups like the League of Women Voters, progressive organizations, and Democratic-leaning commentators. The League of Women Voters allege that the initiative would "disenfranchise a significant number of persons who are legally eligible to cast a ballot" by creating barriers for those without immediate access to citizenship documents. Northwest Progressive Institute call the initiative an "enthusiastic Trump backer" effort by GOP Chair Jim Walsh that's unnecessary and harmful to voter access. Presler, who is gay, co-founded and chaired Gays for Trump and founded and now leads Early Vote Action, has focused on voter registration, turnout, and grassroots mobilization for Republican causes throughout the US. To qualify for the November 2026 ballot, the initiative needs approximately 418,000 valid signatures by July 2026. Video Source: ThePersistence

Another royal expert, Jennie Bond on BBC this morning, claiming to remove Andrew from the line of succession is a "quick" & "simple" process Utter rot The UK Parliament CANNOT act unilaterally We share our monarch with 14 other realms (Canada, Australia, NZ etc.) Under the Statute of Westminster 1931, any change to the succession requires UNANIMOUS consent of all the realms. Each of these 14 independent nations would need to consent to the change. For big states like Canada, this requires new legislation to pass through their Parliaments. For smaller states, this requires formal consent. Securing this is a mamoth task - the last attempt took 11 months - and one which carries significant risks. For example: * debating Andrew and the succession would lead to a renewed push by republicans around the Commonwealth to call for their country to abolish the Monarchy * 1 or more Caribbean nations could require slavery & colonialism reparations as a condition for agreeing to the change * risk of harmful amendments etc. Andrew is 8th in the line of succession and he is far older than the other 7. There is zero chance he will succeed to the throne. (The film "King Ralph" was fiction not fact! Ditto "Kind Hearts Coronets".) Andrew has been stripped of all honours. Removing him from the line of succession would achieve nothing but could bring untold trouble. This is a waste of Parliament's time. If further steps must be taken, Parliament could formally strip Andrew Mountbatten-Windsor of his peerage titles (although he no longer uses them, he remains legally Duke of York (HG not HRH), Earl of Inverness, and Baron Killyleagh Time to abandon this idea. Devoting time to the line of succession seems to be a distraction technique by the Government to divert attention away from other issues (eg Mandelson). Me on GB News:
