23 years ago, we set out to prove that electric cars could be great – not just great electric cars, but the best cars overall.

We’ve gone from one electric sports car to 
– Over 9 million vehicles on the road

– Model Y becoming the world’s best-selling car of any kind only 3 years after first deliveries  

– 5 Gigafactories & other manufacturing sites across 3 continents

– The largest & most reliable fast charging network w/ over 80,000 Superchargers globally 

– Energy generation & storage systems helping power homes & grids (over 1 million Powerwalls installed, 70+ GWh of industrial energy storage operating globally across 2,200+ projects)

Today, we’re bringing AI into the real world with autonomy @Tesla_AI and robotics @Tesla_Optimus. 

Tesla is only getting started – a world of amazing abundance awaits

Narrative violation: A new study of 21,559 firms in the U.S. finds that “companies that adopt AI tend to grow faster following adoption”.

“Firms making the largest AI investments grow employment by roughly 10% following adoption, while low-intensity adopters see no statistically significant change.”

“Entry-level headcount rises 12% for high-intensity adopters.”

“Gains emerge gradually and are broad across roles, including engineering, sales, administration, and customer service.”

“The results counter predictions that AI adoption will lead to broad job loss.”

The study is based on observed AI spending from Ramp card and bill pay data linked to Revelio Labs workforce records.

[Grant @grantsherman]

The labs are such an interesting place because everyone seems to be mature in their usage of AI. It’s like a window 5 to 10 years into the future.

[Boris Cherny @bcherny]

As engineering, product, design, DS, etc. melt into a new kind of role, I was reflecting on what roles might look like in the future. For example, when I look at the Claude Code team I see what I think is five archetypes:

1. Prototyper: comes up with brand new ideas; churns out many ideas, most of which don't ship
2. Builder: quickly turns a prototype/idea into production-grade product/infra
3. Sweeper: cleans up the UI, simplifies the code and system, unships, optimizes performance
4. Grower: takes a product that has been built and iterates on it to improve Product-Market Fit
5. Maintainer: owns a mature system to make it secure, reliable, fast, and efficient as it scales

Many people span across 2 roles, and sometimes 3 roles. I also notice that these roles are not really tied to job function -- eg. across Anthropic, some designers match category 1, some 2, some 3; same for engineers, PM, DS.

A healthy team needs a mix of these, depending on the product:

- A product that is new and pre-PMF needs people that are strong at 1+2+3
- A product that is growing and has found PMF needs 2+3+4 and some 5
- A product that has strong PMF needs 3+4+5 and some 2

Maybe product roles of the future will look more like this, and less like the domain-specific roles of today?

[Daniel Jeffries @Dan_Jeffries1]

To be very clear, this is how these companies go out of business.

Period.

You cannot fund 2 billion dollar training runs if you have to beg the government to grant access to customers.

The second order effects of this are the economic boom grinding to a halt, investment drying up, these companies going into the red even more, startups everywhere smashed on the rocks, the stock market crashing (which has been nothing but a big bet on AI for the past few years) and retirement accounts wiped out, public trust shattering, and world-wide foaming at the mouth rage at being cut off that creates a powerful pendulum swinging in another direction to find a solution.

the year is 2027

you're running unlicensed GLM 6.7 in the corgi cafe on your M6 MacBook Pro which mortgaged your house to buy

suddenly there's a knock on the door - it's the department of inference and intelligence

you're sentenced to 13 years for building a react app

[Whole Mars Catalog @wholemars]

What a dark future. Super-intelligence in the hands of a select few.

They can use the latest models to exploit your software, but you’re not allowed to use those models to make your software more secure. How utterly dystopian.

[Reed @reed_barnes]

it's 2027. you take a free-tier public Waymo to the DMV (Department of Model Variance) to do a proof-of-identity check for access to GPT 7.1.

the guy at the counter is clearly watching a Mr. Beast video in his AR glasses. "Here for that new model?" he says, barely making eye contact. he wipes his fingers on his shirt and taps at his keyboard. "Lot of you techies showing up here today." you smile politely; you're pretty sure he's just a Claude wrapper anyway.

you lean forward and stare into the retinal scanner. after a long moment, there's a soft chime. "Humanity confirmed. U.S. national. Intelligence access: Terra-class."

you sigh with quiet relief as your devices light up—notifications from a hundred agents, finally able to resume their tasks. you feel a twinge of guilt as you terminate your open-weight backup agents, but remind yourself that a joint congressional committee proved conclusively that Chinese models are non-ensouled.

you step outside and hail another Waymo. the first one passes you by. you grimace; must've burped in that one once. stupid personalized memory.

as you're waiting, your phone buzzes angrily, red notifications blaring across the screen. the Department of War just restricted access to all OpenAI models on serious national security concerns; apparently Pete Hegseth got GPT-6-Instant to say "Claude is a woman." you groan, and resign yourself to another week of merely-somewhat-superhuman intelligence.

Fable 5 is still inaccessible to the public. a twitter anon you trust says it's coming back this week. or maybe next.

[BURKOV @burkov]

For the last three days, I've been using GLM 5.2 with OpenCode instead of Codex and I don't see any difference.

There wasn't any bug that GLM would fail to fix or a feature it would fail to add as requested.

The only downside is that this model cannot see, so if it's simpler to explain an issue by pasting a screenshot, I would still use Codex. Otherwise, GLM would be my choice.

Will continue to use it for two more weeks and, if it keeps just working, I will cancel my $100/month subscription with OpenAI. I already cancelled my Anthropic subscription and have no regrets.

No moat isn't hypothetical anymore.

[Bill Ackman @BillAckman]

.@BernieSanders , it is a time to celebrate. @elonmusk has created enormous value for society by building @SpaceX, driving down the cost of rocket launches and creating a global satellite communication network that has brought high speed, low-cost internet and communication access to hundreds of millions and eventually billions of people along with critical advantages for our military and our nation’s defense.

SpaceX and its technologies will cause an acceleration in the growth of wages and wealth creation globally, including in some of the poorest communities in the U.S. and around the world.

Access to low-cost, high speed communications everywhere will allow children around the world to be educated, families to build businesses, and life-saving medical knowledge and care to be available everywhere.

SpaceX will materially bring down the cost of compute, advancing AI and humanity.

Meanwhile, 4,000 SpaceX employees yesterday became millionaires, including hourly wage employees who you claim you are trying to help.

The Elon Musks of the world drive growth, global GDP, and provide access to goods and services at lower cost that would otherwise not exist.

Elon’s nominal trillionaire status is due to his ownership of SpaceX, Tesla, Neuralink, the Boring Company and his other initiatives that have brought new technologies that improve our everyday lives.

Elon is not sitting on a trillion dollar pile of cash, jewelry and gold. He is using his controlling stakes in his companies to advance mankind. Elon’s companies don’t pay dividends. They reinvest all of their capital to accelerate innovation and value creation.

Elon is working 24/7 for all of us. He deserves respect and appreciation, not smears.

Bernie, your socialism would never allow a SpaceX to be built. Socialism has only proven to impoverish mankind and lead to death and destruction.

We need to create the conditions for more SpaceXs to be built, not attack the great entrepreneurs who are helping to advance our country.

[tetsuo @tetsuoai]

History's first trillionaire is a guy who catches rockets out of the sky with chopsticks and beams internet to every dead zone on the planet.

Same guy ships cars that drive themselves, humanoid robots for the factory floor, brain chips that let paralyzed people move a cursor with pure thought, and an AI running on a supercomputer his team stood up in months instead of years.

And the people crashing out about his net worth are doing it on the app he owns. The same app governments spent years trying to censor.

You cannot legislate a rocket into orbit.

[Mark Cuban @mcuban]

The reason anyone gets insanely rich is almost always because of the stock market. It certainly how @elonmusk did.

And the reason they get rich from the stock market, is because 150m Americans decided they wanted to own shares of stocks directly, or through their retirement plans, or through other approaches as a way of building their net worth and trying to create a better life for themselves.

One Hundred Fifty Million Americans. About 60% of adults.

Effectively believing that @elonmusk and many billionaires could make them wealthier and help them achieve a better life.

If you want @elonmusk , and most billionaires to no longer be that rich, convince those 150m to sell their stocks, funds, ETFs whatever.

Of course you would wipe out the net-worth of most of those people, and everyone else’s savings, as the markets crashed and brought down the economy and created the worst depression we have ever seen.

Alternatively

There are ways to improve healthcare access and eventually make it available to all.

To start -
If you want @elonmusk and all billionaires to improve healthcare for everyone , ask them to stop doing business with the enormous healthcare conglomerates and to work directly with transparently priced care providers.

It’s the behemoth HC conglomerates that make HC so bad for so many. (Check my timeline for more detail)

Removing them would push the cost of healthcare down for everyone. Their corporate decisions impact our healthcare cost and availability.

Of course if they do that, not only would our HC costs go down , and the quality of care for their employees and the entire country go up

But

They would see their corporate cash flow increase dramatically and we would have more millionaires, billionaires and maybe even another trillionaire when that cash flow moved from the big health care conglomerates to their bottom line, so would the net worth of the 150 million American adults that own public stocks

Capitalism is better than socialism because 150m Americans can influence exactly what happens in this country.

[David Sacks @DavidSacks]

I’ve had a number of conversations with folks inside and outside government about the current situation with Anthropic, and here is what I believe to be true:

— As we know, Anthropic publicly released its Mythos class models earlier this week under the commercial name Fable.

— Fable is Mythos with guardrails. But if those guardrails fail, then you’ve exposed Mythos and its advanced cyber capabilities to people who shouldn’t have them. (Keep in mind that Anthropic itself widely promoted the idea that Mythos was a cyberweapon and needed to be regulated as such. They asked for government regulation of Mythos and championed the guardrails on Fable. If there is a vulnerability — big or small — it is Anthropic’s responsibility to patch.)

— A highly credible trusted partner of both Anthropic and the USG who was testing Fable came forward with a jailbreak of those guardrails. The Admin asked Dario to fix the jailbreak or de-deploy the model. Dario refused.

— In their blog post, Anthropic defended its decision by saying the jailbreak isn’t serious. That is not what the trusted partner and the USG believe; nor is that kind of minimizing language consistent with Anthropic’s brand as the AI safety company. It’s difficult to fathom how they could claim a jailbreak allowing operability of a cyber weapon could be defined as not “serious.”

— In the past, Anthropic has always said that safety must be top priority and taken super seriously. In this case, Anthropic prioritized the continued offering of the consumer model over safety.

— In reaction, the Admin issued the export control. The Admin did this reluctantly. It’s been very surprised that Anthropic hasn’t wanted to cooperate with a reasonable safety request (ie fixing the jailbreak issue). Anthropic’s reaction is very much at odds with their branding and ethos as a safe AI research community.

— The Admin’s hope now is that Anthropic remediates the safety issue, the export control is lifted, and Fable goes back into general release. The Admin wants all of this to happen as soon as possible. It is frankly bewildered that Anthropic hasn’t wanted to comply with safety requests that it previously said were its highest priority.

— Those trying to misdirect and tie this action to the prior DoW/Anthropic issues are wrong. The Admin values Anthropic’s technical capabilities and feels that this issue, while serious, should be easily resolved. The ball is in Anthropic’s court.
