China is increasingly using hundreds of electric self-driving trucks that run 24 hours a day and can find their own charging stations.
The irony is they’re mining coal and ultimately powered by coal-fired plants. wsj.com/world/asia/these-tru…

Children averaging 5,000 to more than 12,000 steps per day day had fewer mental health symptoms than those taking less than 5,000.
Mental health symptoms were progressively lower across higher step counts with no apparent plateau, even at 12,000+ steps per day.
Brain scans also linked higher step counts to greater thickness in two specific regions of the cortex, the brain’s outer layer.
Daily movement deserves much more attention as a potential way to support kids’ mental health. That's especially clear when you consider that modern-day digital and urban environments provide little opportunity for movement throughout the day.

This is a fantastic point of view on how agents can help us be more social
Worth reading the whole thing. My favorite line (and something I am experiencing with some test agents) “It’s interesting to think of AI agents gossiping about us (as of course human agents do!)”

🚨 OBAMA ON AI: "If we are thinking about AI just in terms of how do we cure cancer or get better energy, you can do that without having agentic AI and having it just roaming free in the internet. The reason you are doing that is because you have to market a product that people will pay money for.
That’s a misalignment between what our society needs and the commercial imperatives that these companies are facing, not because necessarily they’re trying to do bad things, but because they’ve got to justify these valuations.
So, that’s one more reason why it is really important for us to have a competent government and a serious bipartisan conversation around this issue, and we have to do it fast. And I would encourage voters to pay attention to this. If somebody does not have a serious plan for how to deal with this, then they’re not meeting the moment, and you should probably look for somebody else."

Everyone supports public transportation.
They don’t take the bus, of course. It would take twice as long!
Everyone also supports public education.
But apparently children have a civic obligation to learn at half speed to "support public schools"
Maybe we should value kids' time too

MIT published a brutally honest report on what AI is doing to students.
A committee of professors and students spent five months studying how AI changed learning on campus, and the findings read like a warning to every university on the planet.
Study groups are disappearing. Office hours are emptying out. Problem sets and take-home exams no longer prove anything, because AI can produce credible solutions to almost any written assignment in the undergraduate curriculum. Students who lean on chatbots lose mastery and confidence, and some slip into what the report calls cognitive surrender, reaching for AI at the first hint of struggle.
The numbers are rough. 46 percent of surveyed MIT undergrads use LLMs daily. 90 percent worry about their own overreliance. Undergrads who feel AI makes them replaceable now outnumber those who feel it makes them capable.
The committee's answer surprised me. They refused to fight AI with surveillance. The report calls AI detectors unreliable, says lockdown browsers feel like spying, and warns that policing students builds a classroom atmosphere of mutual distrust.
Instead, MIT wants to rebuild education around the things AI can't replace. That means oral exams, semester portfolios, in-person project work, and a required social component in every subject. The report even floats the idea of rethinking grades entirely, since without a GPA to optimize, much of the incentive to cheat with AI evaporates.
The committee warns professors against replacing undergrad research assistants with AI agents just because they're cheaper, because a university exists to grow people, not output.
The most famous tech school on earth admitted the machines broke its way of teaching. Its answer is more humans, not more software.

Rainmaker just produced ~19M gallons of water in Alaska via next-gen cloud seeding over 3 hours of operations.
We are the first company to provably produce precipitation in Alaska. As promised, we’ve linked our white paper and relevant data.
In the future, Rainmaker will protect and restore glaciers with man-made snowfall.
Immediately, this demonstration shows how Rainmaker will add new water to the Colorado River and Great Salt Lake in the coming months.
We turned around this analysis and white paper just a couple days after operating. There are many data sources I want to deepen our understanding of the atmosphere and increase our provable production; we’re building the instruments to collect that data in subsequent operations. But at Rainmaker, we won’t tout LOIs, simulations, or lab tests. What matters is physically measuring that you’ve affected the atmosphere; proving that we’ve produced water. We prefer sharing only the tech that has proven to make more water for farms, industries, and ecosystems in need.
Expect a regular cadence of these from us as we build the best atmospheric science lab in the world. Feedback is welcome in the interim.
Rainmaker Century.

The most alarming thing about this graph is not just the amount of change, but the smooth consistency of the curve. If this were a startup I'd be really confident about their future growth. Unfortunately it is instead the planet we live on.

This is really stupid, and it’s not getting enough attention.
The Trump administration is pulling a working $368 million ocean monitoring system out of the water, equipment taxpayers already bought, built, and sank into the deep ocean.
And they are doing it right when the oceans are behaving in ways that alarm the scientists who study them.
Record-breaking temperatures.
A system of Atlantic currents that may be lurching toward collapse.
The response?
Yank out the instruments and walk away.
That is not budgeting. That is smashing the gauges while the engine is on fire and calling it efficiency.
For what? The Trump administration dressed it up as a “nimbler approach” and “smart lifecycle management,” which is fancy nonsense for “we shut it off and hoped nobody would ask why.” There is no return-on-investment analysis. They cannot show taxpayers save a dime, because the gear is already paid for and the science it produces protects real money and real lives.
The kicker: the same people killing the monitors want to mine the deep sea for minerals. So they are destroying the only tools that could measure what that mining does. That is not an accident.
That is the point. You cannot see the damage if you break the instruments first.

She said no it isn't
I said then what is it about
She did not answer
She said you can't put a dollar value on his teachers his classmates his environment
I said I can the analyst already did slide 6
He flipped to slide 6
She did not look
She said the school is the best in the city

She said our son deserves it
I said our son deserves $83 million
My son walked in
He is five

He said are we modeling pre-tax or after-tax
The analyst opened a new tab
My wife looked at the ceiling
He said what's the discount rate
The analyst set down his pen
She closed her eyes
He said is this the same return assumption from the 529 conversation
The analyst stopped typing
He looked at me
I did not say anything
She stood up
Sat back down
He said dad can I help
I said yes
He pulled up a chair
The analyst handed him a printout
He started reading
My wife watched him read
She watched him for a long time
She said his name
He looked up
She said do you like school
He said the work is too easy and the kids don't ask questions
She did not respond
She looked at the ceiling
She walked out of the room

He said should I follow up Monday sir
I said no follow up needed
He'll be fine

Mankind has always been at the mercy of the weather.
No longer.
Rainmaker is the first company in history to routinely, unambiguously, modify the weather.
Last quarter, we produced >143MM gallons of unambiguously man-made precipitation.
Here’s how we do it 🧵

Alpha School is trying a new entrepreneurial high school track: make $1 million by graduation or get your tuition back
When I say that our current education system is failing our highest potential students - this is what supporting high achievers looks like when it’s done right
Our top students absolutely have the potential to be millionaires before they graduate high school, but today they’re held back by anti-excellence ideologues who insist that we not let anyone pull ahead
Make $1m by graduation.
Or get 100% of your tuition refunded.
That's the promise of the new high school for entrepreneurs Cameron and I are launching this fall through @AlphaSchoolATX.
We need 2-3 coaches to help make it happen.
DM us or apply!

Schools should ban personal devices, social media, passive consumption software, etc
The problem is that they’re going to throw the baby out with the bathwater
It’s like banning “drugs” broadly and not keeping antibiotics, pharmaceuticals, chemotherapy, etc.
Ban screens when used as drugs and digital babysitters.
Keep screens when used as supercharged educational tools.
