A man spends 50 years teaching at MIT.
He knows his time is running out.
So he records one last lecture — everything he knows, distilled into a single hour.
He died 5 months later.
This is that lecture.
The most important hour you'll watch this week. 👇

We’ve reached the point in the matrix where the government officials who are guilty of fraud are creating laws that will imprison the people investigating their crimes.
Incredible.
Elon Musk just weaponized gravity.
The entire trucking industry has a physics leak bleeding billions.
Musk just sealed it.
Most people look at the Tesla Semi and see a cleaner diesel. A truck that swapped a gas tank for a battery.
That is a complete misread of the physics.
Musk: “Let’s say you’re going over a mountain range. In a diesel truck, you actually don’t capture the energy of height or potential energy.”
For a century, freight has fought gravity twice on every mountain.
A diesel truck burns thousands of dollars in fuel clawing its way to the peak. It arrives at the summit loaded with enormous gravitational potential energy.
And what does it do with that energy?
It throws it away as heat.
Musk: “You have to actually spend a lot of money on expensive brakes going down the other side so you don’t run out of control.”
Diesel burns twice.
Fuel going up. Hardware coming down.
A century of logistics, and the descent was never anything but a cost to be survived.
The Tesla Semi doesn’t survive the descent.
It harvests it.
Musk: “An electric semi truck is able to recapture the gravitational potential energy and in fact puts the energy back in the pack.”
Regenerative braking doesn’t just slow the truck. It converts 80,000 pounds of downhill momentum into raw electricity flowing back into the battery.
The mountain stops being an obstacle.
It becomes a power plant.
Here is the thermodynamic reality the market is missing.
Diesel is closed on the descent. There is no version of a combustion engine that turns downhill momentum back into liquid fuel. It is structurally impossible.
Electric is open in both directions. The same system that spends energy to climb gets paid on the way down.
Wall Street keeps pricing the Tesla Semi on a cost-per-mile comparison. Kilowatts versus gallons.
They are solving the wrong equation.
You cannot win a price war against a machine that bills the planet for its own fuel.
NEWS: Tesla has updated its FSD miles tracker to account for a larger vehicle fleet & increased FSD usage.
Tesla's fleet is now driving an average of 19.2 million miles per day on FSD, up from 14.4 million miles per day a couple months ago. That's 1,000 miles every 4.5 seconds.
BREAKING: Tesla has officially released FSD V14.3
I'm downloading it in my Model Y right now. Here's everything that's new:
• Improved parking location pin prediction, now shown on a map with a P icon.
• Increased decisiveness of parking spot selection and maneuvering.
• Rewrote the Al compiler and runtime from the ground up with MLIR, resulting in 20% faster reaction time and improving model iteration speed.
• Enhanced response to emergency vehicles, school buses, right-of-way violators, and other rare vehicles.
• Mitigated unnecessary lane biasing and minor tailgating behaviors.
• Improved handling of small animals by focusing RL training on harder examples and adding rewards for better proactive safety.
• Improved traffic light handling at complex intersections with compound lights, curved roads, and yellow light stopping - driven by training on hard RL examples sourced from the Tesla fleet.
• Upgraded the Reinforcement Learning (RL) stage of training the FSD neural network, resulting in improvements in a wide variety of driving scenarios.
• Upgraded the neural network vision encoder, improving understanding in rare and low-visibility scenarios, strengthening 3D geometry understanding, and expanding traffic sign understanding.
• Improved handling for rare and unusual objects extending, hanging, or leaning into the vehicle path by sourcing infrequent events from the fleet.
• Improved handling of temporary system degradations by maintaining control and automatically recovering without driver intervention, reducing unnecessary disengagements.
Upcoming Improvements:
• Expand reasoning to all behaviors beyond destination handling.
• Add pothole avoidance.
• Improve driver monitoring system sensitivity with better eye gaze tracking, eye wear handling, and higher accuracy in variable lighting conditions.
@elonmusk@Tesla I’m a early adopter of FSD(2019). Purchased Model 3 with HW3. I think any original purchaser of early FSD should have the option of a 1 time transfer to a new Tesla without a deadline. Reward for believing in the Vision! #lovemyfoundationcybertruck
It's funny that people are debating whether a space data center will work without putting a single rocket in space.
It's like ancient Greeks arguing if they could make a piece of aluminum fly faster than the speed of sound.
There's no need for debate since the judge is physics, not humans.
If you add up all the government funding Tesla and SpaceX have ever received, it is only about 1% of the combined value of the companies.
In contrast, if you do that with US and European major aerospace companies, the government money they have received *exceeds* 100% of their value!
Making the dry electrode process work at scale, which is a major breakthrough in lithium battery production technology, was incredibly difficult.
Congratulations to the @Tesla engineering, production and supply chain teams and our strategic partner suppliers for this excellent achievement!
