@99_Colorado @realHGA I congratulate you Diana
It’s all to your credit !
And the father too

@CraigBaird An engineering feat

The Daniel-Johnson Dam in Quebec is the largest multiple-arch buttress dam in the world.
Standing 214 metres tall and 1.3 km long, it contains 2.2 million cubic metres of concrete. It also led to the creation of The Eye of Quebec.
This is the story of the dam.

@wholemars Can we summarize our own posts before publishing ?
Just a idea
English
Can I have an option to shorten it to 140 characters and then display that in the feed

You see those viral clips of Waymos, you seldom see people mention that they eliminate more than 90% of accidents.
Sawyer Merritt@SawyerMerritt
NEWS: Waymo has just announced that their autonomous fleet has now driven a combined 170 million rider-only miles without a human driver as of Dec 2025, up from 127 million in Sept 2025. That's 467,000 miles per day on average. Waymo also released updated safety stats. Locations: • LA: 37.8 million • SF: 53.5 million • PHX: 68.6 million • Austin: 10.7 million

By the time the Roadster is actually delivered, many of the original reservation holders will be in a retirement home

I do think that solving self-driving gets easier every year. Generative AI certainly makes things a lot easier.
However, even despite that, people dramatically underestimate just how hard it is to get to full autonomy. The long tail is extremely long, and you are betting lives.

@wholemars Little do they know how long the road to L4 actually is. They will be lucky if they reach it by 2028. From what I have seen of UHF today it’s going to be a while

@wholemars I will start with a thousand
But 10k is even better

@JCChristopher Good job JC !
The truth must always be exposed, as much as fake news

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.

Tesla Self-Driving needs to be not just safe, but idiot proof.

@yunta_tsai Here is a good example of the team's hard work
An icy, wet road.
If FSD stopped, it would start rolling back down the slope.
There was no room for error

I often think about our winter testing picture. It represents the beauty of the vehicle and the hardness of our grit.
Beauty can grow from hard work.

@AIDRIVR We just can't wait man !!!
You will be one of the first to test it
And you deserve it

FSD 14.3 is in testing now, with wide release in a few weeks!

The media is running a story today about how a Cybertruck “allegedly” crashed on a Texas highway. Spoiler alert, the crash happened while the human driver was in control.
The law firm, which is seeking $1 million, says that last summer Justine Saint Amour was driving her Cybertruck with Autopilot engaged. There’s just one problem — Autopilot is a legacy lane keeping system that never shipped on Cybertruck.
The driver then admits that before the crash they disengaged the system and started driving manually. Indeed, the video shows the truck starting to turn before the driver disengaged and drove into the wall.
Tesla hasn’t officially responded to the lawsuit yet, but available telemetry indicates the driver probably wasn’t paying attention, got startled, and crashed. There doesn’t seem to be any attempt to steer back towards the on-ramp in the video, rather you see the trajectory change from turning with the ramp to driving straight into it.
When you crash your car, people tend to put blame on anyone but themselves. A high profile company like Tesla, with a CEO who is the wealthiest man on Earth? Yeah, they kinds of BS lawsuits happen often.
Let’s wait for more data and discovery to take place, but based on the evidence i’m seeing so far that doesn’t look like something FSD — even an older V13 — would do.

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.
