Introducing the Large Docking Adapter. The future of space is larger space stations, vehicles, and payloads. Designed to support greater overall mass while standardizing module compatibility, the adapter is currently in development at Vast HQ and available for order. vastspace.com/updates/vast-u…

@FSDRoboRides @scotsrule08 @mrfundman @Tesla_AI It's not an intractable problem. They could have a feature in the app to request a partial refund. Tesla can compare the route taken with optimal navigation route and issue a refund for the extra amount incurred. Btw, human drivers make mistakes too, Uber doesn't care.

@scotsrule08 @mrfundman @Tesla_AI Can you imagine if you were paying for this ride per mile in a Robotaxi? How would you go about disputing something like this when you get overcharged? This is a problem that Tesla needs to solve ASAP.

It will cost more than that, and it will still never happen. There is no chance. It is not possible.

In a 60 Minutes report, officials said they now believe the rail line linking L.A. and San Francisco could ultimately cost about $126 billion, more than triple the original price tag approved by voters. ktla.com/news/californi…

It’s hilarious how proud of themselves people are for noticing the very first thing anyone would notice about space data centers. I too had the thought “what about cooling” the first time I saw the idea, then I saw huge companies betting on it and assumed I was missing something rather than that no one at SpaceX etc had the BRILLIANCE I had to notice this obvious phys 101 objection, because I’m not a moron.
And yeah, turns out you can make radiators work.

Why space servers FAIL Execs want to put data centers in space, but there's a massive physics problem: vacuums have no convection cooling. Discover why cooling servers in space relies purely on infrared radiation! Big thanks to @ThreatLocker for sponsoring my trip to ZTW26 and also for sponsoring this video.

@TS86142 @NASAAdmin @NASAMoonBase 3.5 km/hr? I guess the good thing is that if it breaks down you can walk back faster than it took to get you there.

@NASAAdmin @NASAMoonBase Excited that Japan is part of this effort, providing the Toyota/JAXA pressurized rover for astronauts on the Moon.
English
To build a sustained human presence on the Moon, we are building @NASAMoonBase, prioritizing surface operations and scalable infrastructure.
- Frequent robotic landings and mobility testing including MoonFall drones
- Starting in 2027 nearly monthly cadence of equipment and rovers with scientific payloads landing on the Moon.
- Investments in power, communications, and surface mobility
- Scalable infrastructure to support long-term human presence
The objective is clear: build the foundation for an enduring lunar base and take the next step toward Mars.

@lrocket @amitisinvesting SpaceX could easily hit $100 trillion or more in value.

@amitisinvesting It isn't about current revenue, it is about the first and second derivatives of revenue

Ford CEO in new interview:
“We'll have an all-electric, affordable vehicle to compete with Model Y and Model 3. I think there's nothing else like it on the market. We started a skunkworks team 4 years ago. They were basically Formula 1 and Tesla people. That vehicle is radically different. I'm really excited to show everyone maybe late this year or (early) next year. It will be coming out next year.”

My biggest disengagements aren't ones I do, but rather the redhands of doom, that fsd 14.x does frequently in the rain in certain situations.
10 times on 14.2.2.5 and 7 other times on other versions of 14.x.
Outside of that, i've only had one safety related disengagement, where I disengaged, in the last 10,000 miles in over 99% fsd driven.
English
This thread that @DirtyTesLa started is worth discussing in more detail.
The number of people demonstrating very high percentages of FSD utilization over thousands of miles of driving is incredible to see. To me this IS the use case for consumers. Let the @Robotaxi cook, and let Cybercab grow up.
Most of us just want safe autonomous driving with low nags so we can make our commutes, our road trips, and daily lives easier, less stressful and MUCH safer.
@Tesla_AI has delivered this in my opinion with FSD V14.2x. It's not perfect. Nav needs help, and many other areas I know where to help it with a manually initiated lane change to keep it out of trouble. But my drives are sooo much better these days, and my 99% FSD utilization proves it.
Bravo Zulu @Tesla_AI

"Coastliner" is an epically great name for @United's new airplane. It evokes the old, great age of flight—which is gradually getting rebuilt anew.
I'm looking forward to flying on one of these.

At any given time there are ~12,000 planes up in the air.
Another way to look at it is: ~150,000 take offs a day, more than one every second.
When you look at aviation, then 10k Starship launches per year suddenly doesn’t feel far fetched anymore.

@aaronburnett @LimitingThe How’s it same team? Is Elon hiring Tom Mueller to lead semiconductor fab design? To make this work Elon “simply” has to locate and hire the top semiconductor manufacturing people in the world from industry and also maybe (exiting) academia. Ask around, see who is publishing what.
English
@LimitingThe I know it’s reasoning by analogy (so dangerous) but you’d believe this team has a shot at replicating then massively scaling what others have already proven is possible.
English
TSMC mskes thousands of different chips for hundreds of customers.
Terafab will make two chips.
This massively simplifies the factory and allows them to focus on trying different iterations of those two chips to accelerate production and reduce costs.
Elon Musk@elonmusk
Given that several companies make advanced chips, but no companies have ever made fully reusable rockets or achieved SpaceX scale, I think Starship is harder, but we shall see. Terafab will technically be two fabs, each making only one chip design. This greatly simplifies process flow and allows more linear, adjacent movement of the FOUP. A super high production rate allows us to test very quickly what steps can be deleted, simplified or sped up, even after the design is fixed. Current fabs are extremely conservative, operating on rigid historical heuristics, which are mostly, but not all, correct. Anything that is a rate limiter at the machine level means that machine will be redesigned, unless already at limit of physics. Having new iterations of a chip design be produced every day in the research fab (with <7 day lag) means being able to try out many high risk, high return ideas. Etc In any event, there is no other way to reach extreme scale, so either we make Terafab or we will be stuck at the ~20% chip/memory output growth per year of the current industry.
