Cybercabs have no steering wheels or pedals. They are designed and built for maximally efficient autonomous operation.
Driving around Austin, Texas with my 5-year-old and 8-year-old when we spotted a driverless Tesla Cybercab in the wild. So naturally… we started chasing it. My kids grabbed the phone and filmed the whole thing. This is literally their footage. And then it hit me… They may be two of the youngest kids in the world to ever see a driverless Cybercab operating on public roads. Something they would not see today if they were at school today. I don’t think they fully understand how big this moment is yet. They just see a cool car driving itself. But this is the world they’re going to grow up in. A world where cars drive themselves, Robotaxis pick you up, and transportation looks completely different from what Daddy grew up with. To me, this feels like the future. To them, it might just feel normal. One day they’ll look back at this video and realize they were there when that future was just beginning.

Warning: This Carl Sagan explaination has caused existential crises. He explains how 5th dimensional beings perceive 3D creatures, and the implications are so disturbing, I paused it three times. He said: A being from the 5th dimension could reach into your locked house, take an object off your kitchen table, and place it in orbit around Jupiter without ever crossing a wall, a door, or the vacuum of space. People ridiculed when Carl Sagan said this. But, he was walking through the cleanest piece of geometric logic in modern physics, and most people who watched it never realized what he actually gave them. The demonstration starts small. Imagine a flat creature living on a sheet of paper. Its entire universe is length and width. It has no concept of "up" because up doesn't exist in its world. The direction is literally unthinkable to its nervous system. Now take a three-dimensional apple and push it slowly through the paper. What does the flat creature see? A dot appears from nowhere. The dot expands into a circle. The circle grows, shrinks, then collapses back into nothing. The apple was always whole. The flatlander only ever perceived cross-sections of something its dimensions could not contain. That's the entire trick. Sagan's move was to rotate the analogy upward and let you feel the vertigo yourself. You are the flatlander. Your body, your brain, your sensory apparatus evolved to process three spatial dimensions and one directional slice of time. Anything existing in a higher dimension would pass through your world the same way that apple passed through the paper. As fragments, apparitions, sudden appearances, inexplicable disappearances. A 4D being could see every organ in your body simultaneously from the outside, the way you can see every room of a dollhouse at once from above. A 5D being could observe your entire lifetime from every version of you from infant to corpse like a single unmoving sculpture stretched across time. What's interesting is it's a direct consequence of how dimensions mathematically nest inside one another. Every dimension has full access to the interior of the one below it. A 3D hand can touch any point inside a 2D square without crossing its edges. A 4D hand could touch any point inside your sealed body without breaking your skin. Sagan has really handed us a quiet reframe of every "impossible" phenomenon humans have reported for thousands of years like visions, presences, objects moving through walls, beings that seem to know your past and future. Though his Geometry doesn't confirm any of it. But it removes the argument that such things would violate physics.

The existential risk that really scares me, due to its likelihood and consequences, is an unrecoverable dystopia. One, permanent world government that will never be overthrown. Space colonisation is a really good hedge against that one.

Our society has gaslit its young women about their reality in terrible and destructive ways.
Young women's perceptions about how they are treated (particularly by men) have changed radically over the last 15 years. In 2011, ~75% of young women believed women are treated w/ respect in America. By 2024, however, that number had fallen to only 40%.

Great research, but unless you are an academic, this is pretty generally appreciated. Anyone who has been raising kids intimately knows how much they take after them, in personality as well as looks.

The degeneration of Nature, Science, NEJM, and Scientific American into woke propaganda dispensers (and their refusal to publish normie, centrist, common-sense responses) is a scientific scandal.

This is what Tesla’s Robotaxi app looks like when your Cybercab arrives. The screen glows to match whatever the color the RGB front light bar is on the Cybercab, while an arrow points to where the vehicle is located. You can also flash the lights and honk the horn to identity it.

It is indeed a disgrace. Those publications have an obligation to adhere to the truth and yet have become woke propaganda outlets.

The second law of thermodynamics says that the total entropy of a closed system cannot decrease. Entropy is a measure of how many microscopic states are possible in a system. At first, black holes might seem to have very little entropy because they are described by only a few properties, such as their mass, charge, and angular momentum. However, in 1972, physicist Jacob Bekenstein proposed that black holes should have entropy. His argument was based on the second law of thermodynamics. If an object with entropy falls into a black hole, its entropy would no longer be directly accessible outside the black hole. If the black hole had no entropy of its own, this could lead to a decrease in the total entropy of the universe, which would conflict with the second law. So, how much entropy does a black hole have? In 1974, Stephen Hawking showed that black holes have a temperature and emit thermal radiation, now called Hawking radiation. This means that black holes have thermodynamic properties. Using the relationship between energy, temperature, and entropy, physicists found that the entropy of a black hole is proportional to the area of its event horizon. This result is known as the Bekenstein–Hawking formula: S = A/4ℓₚ² where S is the black hole's entropy, A is the area of its event horizon, and ℓₚ is the Planck length. The important point is that black holes do not violate the second law of thermodynamics. Instead, they can contain an extremely large amount of entropy. For a given region of space, a black hole represents the maximum possible entropy allowed by known physics. So, although a black hole looks simple from the outside, its entropy can be extremely large.

Talk to @Grok in your Tesla
Today I drove past a house for sale that looked nice ... So I asked Grok in the Tesla how much it was. It pulled the listing, price, beds/baths, square footage, days on market, and market analysis — all while FSD kept driving. No phone. No searching. Just talking.

Super happy to share our intention to join forces with NVIDIA in a $12,930,300,000 acquisition 💛💚 10 years after starting Hugging Face, open-source AI is at an inflection point. Thanks to the community, we’ve shown that it can be a complement, and even an alternative, to closed-source APIs. But for it to happen at larger scale, it needs more compute, more support, more collaboration and more visibility. That’s why we went to talk to Jensen, who offered to do exactly that with us. In addition to doubling down on NVIDIA’s massive contributions to open-source AI (I called them the “King of American open-source AI” earlier this year), they’ve committed to strongly supporting Hugging Face and our mission while keeping the platform open, independent and compute agnostic. The founders and the team are all staying to keep pushing this mission forward. Together, we think we can make open source the default way to build AI, with the goal of empowering 100 million AI builders to own their intelligence rather than rent it. Excited about the next 10 years! 🤗🤗🤗

Exciting day for NVIDIA and @huggingface. Open models strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty. They allow every developer, startup, university, industry and country to build with, customize and benefit from AI. Thank you @ClementDelangue for coming to me. NVIDIA is going to be a great home for Hugging Face, its community and the future of open models. 🤗 blogs.nvidia.com/blog/nvidia…
