New Elon Musk essay: Tesla CEO’s current thoughts on technology and humanity
It’s been a while since Elon Musk published an extensive blog post outlining his stance on a specific topic. On the official Tesla website, his last blog post was on August 24, 2018, when he explained his decision to keep Tesla a publicly-traded company. Fortunately, a new Elon Musk essay has been posted in China, outlining the Tesla CEO’s thoughts on a number of topics — from sustainability, the Tesla Bot’s real-world use, Neuralink’s focus on the disabled, and SpaceX’s exploration aspirations.
The new Elon Musk essay was published in China Cyberspace, the Cyberspace Administration of China’s (CAC) flagship magazine. A translation of the essay was posted by Yang Liu, a journalist from the state-owned news agency Xinhua, on the Beijing Channel blog. As could be seen in Liu’s post, Musk actually discussed a number of topics in detail.
In a way, the publication of the new Elon Musk essay in the CAC’s flagship magazine is significant. As noted by The Register, Musk’s essay suggests that Chinese authorities approve of the Tesla CEO’s positions on the topics he discussed. Only a few other foreign entrepreneurs would likely be given the same honor.
Following is the full text of Elon Musk’s new essay.
Believing in Technology for a Better Future
Thank you for the invitation from China Cyberspace magazine. I am pleased to share with my Chinese friends some of my thoughts on the vision of technology and humanity.
Posted by Elon Musk
As technology accelerates, it may one day surpass human understanding and control. Some are optimistic and some are pessimistic. But I believe that as long as we are not complacent and always maintain a sense of urgency, the future of humanity will be bright, driven by the power of technology. It is like a self-fulfilling prophecy: if humans want to make the future good, they should take action to make it good.
I want to do everything we can to maximize the use of technology to help achieve a better future for humanity. To that end, any area that contributes to a sustainable future is worthy of our investment. Whether it’s Tesla, Neuralink, or SpaceX, these companies were all founded with the ultimate goal of enhancing the future of human life and creating as much practical value for the world as possible—Tesla to accelerate the world’s transition to sustainable energy, Neuralink for medical rehabilitation, SpaceX for making interstellar connections possible.
Clean Energy: The Future of Sustainability
The starting point for my thinking about clean energy is how to create and store energy sustainably and for the long term, and how to provide a constant source of power for the future of productive life. In my view, the future of sustainable energy involves three components.
The generation of sustainable energy. The sun is like a giant fusion generator, from which mankind currently exploits a tiny amount of energy. In the long run, solar energy will become the main source of energy for human civilization. Of course, wind, hydroelectric, geothermal, and nuclear power are also useful energy supplements.
The storage of sustainable energy. Given the change of day and night and the change of weather, we need a lot of fixed battery banks to store solar and wind energy, because the sun does not shine all the time, and the wind does not blow all the time, energy needs to be stored in a large number of fixed battery banks.
Electrified transportation. Full electrification of transportation, including cars, planes, and ships. Electric rockets may be more difficult, but we may be able to manufacture the propellant used in rockets from sustainable energy sources. Eventually, the world economy will be run entirely by sustainable energy sources.
The world is on track for a sustainable energy transition, and humanity should continue to accelerate the process. The faster this transition is achieved, the less risk humanity poses to the environment and the more it will gain. When clean energy is available, carbon sequestration and desalination will be cheaper, climate change and water shortages will be solved, and when fossil fuels are out of the picture, the skies will be cleaner, the world will be quieter, the air will be fresher, and the future will be brighter.
Solar power, battery packs, and electric vehicles paint a rosy picture. Next, we need to focus on the limiting factors. The electrification of cars has become a consensus among nations, but battery support on a terawatt-hour scale is needed to roll out pure electric vehicles around the globe. According to our estimates, the world needs about 300 TWh of battery storage to achieve a transition to sustainable energy. The biggest difficulty in advancing sustainable energy lies in the large-scale production of lithium battery cells. Specifically, from the mining and element refining to battery cells coming off of the production line and finally assembled into battery packs, this is a complex process that is restraining the rapid development of a sustainable energy economy.
As a pioneer and innovator focusing on energy innovation technology, Tesla was founded to solve the problem of energy innovation. On the one hand, we create integrated sustainable energy products from the three segments of energy production, storage and use; on the other hand, we are committed to redefining battery manufacturing by innovating and developing advanced battery technology to remove restrictions on battery capacity. I believe that the world will transition to a sustainable future through a combination of solar and wind energy plus battery storage and electric vehicles. I am pleased to see more and more companies joining this field. Chinese companies will be a force to be reckoned with in the cause of energy innovation.
Humanoid Robots: Doing What Humans Do
Today’s cars are increasingly like smart, web-connected robots on wheels. In fact, in addition to cars, humanoid robots are also becoming a reality, with Tesla launching a general-purpose humanoid robot (Tesla Bot) in 2021. The Tesla Bot is close to the height and weight of an adult, can carry or pick up heavy objects, walk fast in small steps, and the screen on its face is an interactive interface for communication with people. You may wonder why we designed this robot with legs. Because human society is based on the interaction of a bipedal humanoid with two arms and ten fingers. So if we want a robot to adapt to its environment and be able to do what humans do, it has to be roughly the same size, shape, and capabilities as a human.
Tesla Bots are initially positioned to replace people in repetitive, boring, and dangerous tasks. But the vision is for them to serve millions of households, such as cooking, mowing lawns, and caring for the elderly.
Achieving this goal requires that robots evolve to be smart enough and for us to have the ability to mass produce robots. Our “four-wheeled robots” – cars – have changed the way people travel and even live. One day when we solve the problem of self-driving cars (i.e., real-world artificial intelligence), we will be able to extend artificial intelligence technology to humanoid robots, which will have a much broader application than cars.
We plan to launch the first prototype of a humanoid robot this year and focus on improving the intelligence of that robot and solving the problem of large-scale production. Thereafter, humanoid robots’ usefulness will increase yearly as production scales up and costs fall. In the future, a home robot may be cheaper than a car. Perhaps in less than a decade, people will be able to buy a robot for their parents as a birthday gift.
It is foreseeable that with the power of robots, we will create an era of extreme abundance of goods and services, where everyone can live a life of abundance. Perhaps the only scarcity that will exist in the future is for us to create ourselves as humans.
Neuralink: Empowering the Disabled
Some of our Chinese friends may not be as familiar with Neuralink as with electric cars. These companies focus on developing computer-human brain fusion technologies, developing brain chips the size of coins, similar to wearable devices such as smartphones, except that they integrate more deeply with the user’s body—recording and stimulating brain activity through implants in the cerebral cortex.
At this stage, the technology is helping injured people on an individual level. We have received many saddening letters: a 25-year-old young man was in the prime of his life when he had a motorcycle accident that left him unable to eat on his own, which is a great grief for the individual and the family. In light of this, brain-machine interface technology will be focused on curing or alleviating brain injury and other related disorders in the years to come. For example, it could help restore sensory or motor function to limbs of those with spinal injuries and mental system disorders or allow quadriplegics to use their brains to easily operate computers or cell phones.
This technology can also improve a wider range of brain injury problems, whether these disorders are congenital or accidental, or caused by age and external stressors, including severe depression, morbid obesity, sleep problems, and underlying schizophrenia, all of which are expected to be alleviated by human-computer devices.
With the development of brain-machine interface technology, in the long term, this connection is expected to expand the channels of communication between the outside world and the human brain, “accessing” more brain regions and new neural data. This technology could allow humans to effectively integrate with artificial intelligence and ultimately expand new ways for humans to interact with the world, themselves and others. Even if the goal of human-machine integration is difficult to achieve, brain-machine interface technology could be of great value in the field of medical rehabilitation.
Space Exploration: The Possibility of Cross-Planet Habitats
Finally, my greatest hope is that humans create a self-sustaining city on Mars. Many people ask me why I want to explore outer space and turn humans into multi-planetary creatures. In the vast universe, human civilization is like a faint little candle, like a little shimmering light in the void. When the sun expands one day and the Earth is no longer habitable, we can fly to a new home in a spaceship. If humans can inhabit other planets, it means that they have passed one of the conditions of the great screening of the universe, then we will become interplanetary citizens, and human civilization will be able to continue.
The first step toward interplanetary habitat is to reduce the cost of travel, which is what SpaceX was founded to do – first by building recoverable rockets and then by building reusable mega-ships with ever-increasing carrying capacity. As of earlier this year, SpaceX had successfully reused 79 rockets to deliver cargo to the space station and send ordinary people into space. We have also designed and built the largest launch vehicle in history, the Starship, which can carry 100 passengers and supplies at a time. In the future, we plan to build at least 1,000 Starships to send groups of pioneers to Mars to build a self-sustaining city.
As technology continues to change lives at an accelerating pace and the world evolves, life is more than simply solving one problem after another. We all want to wake up in the morning full of anticipation for the future and rejoice in what is to come. I hope more people will join us in our fight to accelerate the world’s transition to sustainable energy. I also welcome more like-minded Chinese partners to join us in exploring clean energy, artificial intelligence, human-machine collaboration, and space exploration to create a future worth waiting for.

Tesla’s golden era is no longer a tagline
Tesla “golden era” teaser video highlights the future of transportation and why car ownership itself may be the next thing to change.
The golden age of autonomous ridesharing is arriving, and Tesla is making sure we can all picture a future that looks like the future. A recent teaser posted to X shows a Cybercab parked outside a home, and with a clear message that your everyday life may soon look like this when the driverless vehicles shows up at your door.
Tesla has begun the rollout of its Robotaxi service across US cities, and the production of its dedicated, fully-autonomous Cybercab vehicle. The first Cybercab rolled off the Giga Texas assembly line on February 17, 2026, with volume production now targeted for this month. Additionally, the Robotaxi service built around it is already running, without human drivers, in US cities.
Tesla Cybercab production ignites with 60 units spotted at Giga Texas
The Cybercab is built without a steering wheel, pedals, or side mirrors, designed from the ground up for unsupervised autonomous operation. Musk described the manufacturing approach as closer to consumer electronics than traditional car production, targeting a cycle time of one unit every ten seconds at full scale.
Drone footage from April 13, 2026 captured over 50 Cybercab units on the Giga Texas campus, with several clustered near the crash testing facility. Musk has noted that Tesla plans to sell the Cybercab to consumers for under $30,000, and owners will be able to add their vehicles to the Tesla robotaxi network when not in personal use, potentially generating income to offset the vehicle’s purchase cost. That model changes the math on vehicle ownership in a meaningful way, making a car something closer to a depreciating asset that can also earn by paying itself off and generate a profit.
During Tesla’s Q4 earnings call, the company confirmed plans to expand the Robotaxi program to seven new cities in the first half of 2026, including Dallas, Houston, Phoenix, Miami, Orlando, Tampa, and Las Vegas. The service already runs without safety drivers in Austin, and public road testing of the Cybercab has expanded to five states, including California, Texas, New York, Illinois, and Massachusetts.

Tesla’s last chance version of the flagship Model X is officially gone
The Signature Edition was no ordinary Model X Plaid. Offered exclusively by invitation to select existing Tesla owners, it represented the final production batch of the current-generation Model X before manufacturing at Fremont ends.
Tesla enabled a last-chance version of its two flagship vehicles, the Model S and Model X, over the past few weeks. The Model X, the company’s original SUV, is officially gone.
Tesla has officially closed the book on its most exclusive send-off for the Model X. The limited-run Model X Signature Edition—priced at $159,420 before fees and limited to just 100 units—is now sold out, with reservations closed as of April 16.

The Signature Edition was no ordinary Model X Plaid. Offered exclusively by invitation to select existing Tesla owners, it represented the final production batch of the current-generation Model X before manufacturing at Fremont ends.
Every unit featured an exclusive Garnet Red exterior paint, unique badging, and a standard six-seat configuration. With full Plaid powertrain specs—Tri-Motor All-Wheel Drive, over 1,000 horsepower, and blistering acceleration—it was positioned as a collector’s item for loyalists who wanted one last shot at owning a piece of Tesla history.
The timing is no coincidence.
Tesla announced earlier this year that it would discontinue regular production of both the Model S and Model X to repurpose the Fremont factory’s dedicated lines for mass production of its Optimus humanoid robots.
Elon Musk has repeatedly emphasized that Optimus could ultimately become more valuable to the company than its vehicle business, with ambitions to build hundreds of thousands of units annually.
The Signature Editions served as a final “runout” series: 250 for the Model S and only 100 for the Model X, all built to the highest Plaid specification before the line is converted.
Deliveries of the remaining Signature units are scheduled to begin in May 2026. For buyers who secured one, it’s the ultimate swan song for a vehicle that helped define Tesla’s early luxury EV dominance.
Launched in 2015, the Model X introduced falcon-wing doors, a panoramic windshield, and class-leading performance that turned heads and set benchmarks. While newer models like the Cybertruck and refreshed Model Y have taken center stage, the Model X Plaid remained a halo product for those seeking maximum range, space, and speed in an SUV package.
With inventory of standard Model X units already nearly exhausted across the U.S., the rapid sell-out of the Signature Edition underscores enduring demand for Tesla’s premium flagships even as the company pivots toward robotics and autonomy.
For enthusiasts, these 100 garnet-red SUVs will likely become instant collector’s items—tangible reminders of the vehicles that built the brand before Tesla’s next chapter fully begins. The last chance is gone, but the legacy endures.

Tesla Optimus V3 hand and arm details revealed in new patents
Two new patents, which were coincidentally filed on the same day as the “We, Robot” event back in October 2024, protect Tesla’s mechanically actuated, tendon-driven architecture.
Tesla is planning to soon reveal its latest and greatest version of the Optimus humanoid robot, and a series of new patents for the hands and arms, with the former being, admittedly, one of the most challenging parts of developing the project.
Two new patents, which were coincidentally filed on the same day as the “We, Robot” event back in October 2024, protect Tesla’s mechanically actuated, tendon-driven architecture.
The designs relocate heavy actuators to the forearm, route cables through a sophisticated wrist design, and employ innovative joint assemblies to achieve human-like dexterity while enabling lightweight construction and high-volume manufacturing.
Core Tendon-Driven Hand Architecture
The primary patent, which is titled “Mechanically Actuated Robotic Hand,” details a cable/tendon-driven system.
Actuators are positioned in the forearm rather than the hand. Each finger features four degrees of freedom (DoF), while the wrist adds two more.
Tesla’s Optimus V3 robot hand looks to have been revealed in a new international patent published today.
The patent describes a tendon/cable-driven hand:
• Actuators in the forearm
• Each finger has 4 degrees of freedom
• The wrist has 2 degrees of freedom
• Tendon-driven… pic.twitter.com/eE8xLEYSrx— Sawyer Merritt (@SawyerMerritt) April 16, 2026
Three thin, flexible control cables (tendons) per finger extend from the forearm actuators, pass through the wrist, and connect to the finger segments. Integrated channels within the finger phalanges guide these cables selectively—routing behind some joints and forward of others—to enable independent bending without unintended motion.
Patent diagrams illustrate thick cable bundles emerging from the wrist into the palm and fingers, with labeled pivots and routing guides. This setup closely mirrors human forearm-muscle and tendon anatomy, where most hand control originates proximally.
Advanced Wrist Routing Innovation
One of the standout features is the wrist’s cable transition mechanism. Cables shift from a lateral stack on the forearm side to a vertical stack on the hand side through a specialized transition zone.
Boom! @Tesla_Optimus 의 3세대 구조로 추정되는, 로봇 팔 및 관절에 대한 특허가 공개되었습니다.
아티클 작업에 들어가겠습니다.
1년 넘게 기다려 온, 정말 귀한 특허인데, 조회수 100만대로 터져줬으면 좋겠네요. 😉@herbertong @SawyerMerritt@GoingBallistic5 @TheHumanoidHub pic.twitter.com/CCEiIlMFSX
— SETI Park (@seti_park) April 16, 2026
This geometry significantly reduces cable stretch, torque, friction, and crosstalk during combined yaw and pitch wrist movements — common failure points in simpler tendon systems that cause imprecise or jerky motion.
By minimizing these issues, the design supports smoother, more reliable multi-axis wrist operation, essential for complex real-world tasks.
Companion Patents on Appendage and Joint Design
Two supporting patents provide additional depth. “Robotic Appendage” covers the overall forearm-to-palm-to-finger assembly, with a palm body movably coupled to the forearm and finger phalanges linked by tensile cables returning to forearm actuators. Tensioning these cables repositions the phalanges precisely.
“Joint Assembly for Robotic Appendage” describes curved contact surfaces on mating structures paired with a composite flexible member. This allows smooth pivoting while maintaining consistent tension, enhancing durability, and simplifying assembly for mass production.
Executive Insights on Hand Development Challenges
Tesla executives have consistently described the hand as the most difficult component of Optimus.
Elon Musk has called it “the majority of the engineering difficulty of the entire robot,” emphasizing that human hands possess roughly 27–28 DoF with an intricate tendon network powered largely by forearm muscles. He has likened the challenge to something “harder than Cybertruck or Model X… somewhere between Model X and Starship.”
In mid-2025, Musk acknowledged that Tesla was “struggling” to finalize the hand and forearm design. By early 2026, he stated that the company had overcome the “hardest” problems, including human-level manual dexterity, real-world AI integration, and volume production scalability.
He estimated the electromechanical hand represents about 60 percent of the overall Optimus challenge, compounded by the lack of an existing supply chain for such precision components.
These patents directly tackle the acknowledged pain points: relocating actuators reduces hand mass and inertia for better speed and efficiency; advanced wrist routing and joint geometry address friction and crosstalk; and simplified, stackable parts visible in the diagrams indicate readiness for high-volume manufacturing.
Implications for Optimus Production and Leadership
Collectively, the patents portray the Optimus v3 hand not as a mere prototype, but as a production-oriented system engineered from first principles.
The 22-DoF architecture, forearm-driven tendons, and crosstalk-minimizing wrist deliver a clear competitive edge in dexterity. They align with Musk’s view that high-volume manufacturing is one of the three critical elements missing from most other humanoid projects.
For Optimus to become the most capable humanoid robot, its hand needed to replicate the useful and applicable design of the human counterpart.
These filings demonstrate that Tesla has transformed years of engineering challenges into patented, elegant solutions — positioning the company strongly in the race toward general-purpose robotics.
