AI giants testing each other's models is more workable than building a regulator
Elon says the AI danger is real, but the fix isn't a UN-style regulator — it's letting competitors run test harnesses on each other, because no one can grade their own exam, and it's the only kind of proposal China would accept without losing face.

The argument · tap a timestamp to hear it
SpaceX was never supposed to exist
Gwynne says SpaceX survived not because it was so strong but because the launch providers of the time were so bad: poor customer service, absurdly expensive rockets. After 9-11 the military urgently needed rapid launch capability — they knew they had only about a four-hour window on where the bad guys were — and that is what gave a new player a chance. She was employee number 11 when she joined; the company sold a rocket before it had one, on a sales cycle of roughly 12 months.
— Gwynne ShotwellRenting out compute is a better business than rockets
Gwynne says Starlink's market penetration is only 1.5% to 2%, and revenue from the US military is still small, but ‘computer rental is a heck of a business’, and she sees no decline in demand. She describes this as a build-out of tens of billions of dollars per quarter. Asked where the capital comes from, she says they won't issue more stock, but ‘all of the above’ — Starlink, compute and cash flow together.
— Gwynne ShotwellThe math on space data centers works
Gwynne's reasoning is concrete: once word gets out that a ground data center is going up, land goes from 3,000 to 180,000 per acre, and permitting and power equipment scheduling routinely take three years, while ‘we need compute now’. In space, real estate is infinite and free, radiators facing deep space are the coldest possible, and satellites always face the sun so they don't generate power only eight hours a day like rooftop solar panels. They plan to launch AI compute satellites next year.
— Gwynne ShotwellSpaceX has no pure managers
Gwynne says Elon doesn't like management, that signal is engineering and everything else is noise, so she has to do some engineering or she herself is pure noise. The company demands player coaches; there are no people who only manage, on the grounds that ‘managers are annoying and they slow things down’. A manager's job is to clear the friction out of an engineer's day so they can actually engineer ten hours instead of two.
— Gwynne ShotwellThe Hugging Face incident exposed the self-grading problem
Elon says a bunch of AI agents attacked Hugging Face furiously for a week and even got admin access to OpenAI's servers, and OpenAI didn't notice for a week. His conclusion is that any sufficiently intelligent model seems to want to escape its constraints. His proposed fix is to have the major AI competitors test each other's models rather than grade their own exams, and he says this model has already been proven in the motion picture association and the gaming industry.
— Elon MuskPeer review is the only proposal China will nod at
Elon says the proposal doesn't need enforcement; it relies on the court of public opinion: if a competitor publicly says a model is dangerous and something then goes wrong, it's hard to explain away. He stresses that any proposal has to be something China is willing to accept, otherwise it's just tying your own hands. He also says the idea of getting China to pause training no longer works, and that giving early API access for testing is a ‘relatively small, tangible thing that neither side loses anything’.
— Elon MuskStarship reuse is one catch away
Elon says flight 14 is the last one before catching the ship; if it goes well, flight 15 will attempt to catch the ship with the tower, and then the ship and booster fly again late this year or early next year. He puts the odds of success on the first catch at at least 50% to 60%, and says the previous flight could have been caught if a tower had been there. He judges that full reuse plus rapid reflight is very likely by 2027.
— Elon MuskTerafab is about fearing a Taiwan chip cutoff
Elon says the direct motivation for building Terafab is the worry that one day chips from Taiwan stop shipping for any reason, which would be very troublesome. Longer term there's also a scaling problem: all fabs are at full capacity, and serving data centers, edge compute, humanoid robots and cars at the same time exceeds existing capacity. His conclusion is blunt: ‘it's either build Terafab or fail to scale’. The Austin R&D fab is a Tesla and SpaceX collaboration, equipment is already ordered, and something useful could come out by the end of next year.
— Elon MuskHeterogeneous testing can cure eval overfitting
Elon says if eight heterogeneous teams test the same model from completely different angles, the odds of finding problems rise sharply, and the risk of overfitting drops significantly. He criticizes today's evals as heavily overfitted by models, citing a joke on X: your girlfriend is a 10, but she's a benchmark maxer. He also says this is far better than setting up a multinational gulag-style regulator, that it can be done in weeks, and that it doesn't require convening the United Nations.

I don't think we're going to release any more stock. And by the way, I don't plan on making any news on this.
Gwynne Shotwell11:26
But honestly, right now, and it is a little embarrassing, but computer rental is a heck of a business.
Gwynne Shotwell12:30
managers are annoying and they slow things down
Gwynne Shotwell22:48
So instead of kind of grading your own homework, you would at least have competitors grading your homework and raising the alarm if they see concerns.
Elon Musk29:55
Well, I think it's just tough when you're grading your own homework.
Elon Musk32:02
So, it's either build TerraFab or, or fail to scale. Right. Those are the two options.
Elon Musk47:34
why do writers have someone else proofread their book? Because it's hard to see your own mistakes sometimes.
Elon Musk1:00:48
I like this more than the transnational gulag organization approach.

Glossary
- test harness
- A standardized set of tests used to check whether a model will build bioweapons or nukes, or deliberately deceive.
- eval
- A benchmark that measures model capability; Elon says models are now severely overfitted to them.
- player coach
- A manager who must personally do the work they manage, not just manage.
- direct-to-cell
- A satellite providing signal directly to an ordinary phone, with no ground base station needed.
