Harvard and MIT just built an AI simulation containing 8.3 billion virtual people, roughly the entire population of Earth.
They call it MatrAIx.
It is a population-scale digital simulation infrastructure powered by frontier models like GPT and Claude.
They mapped out an insanely detailed dataset called Persona 8B. It contains 8.3 billion unique digital profiles.
Every single persona is defined across 1,290 categorical dimensions.
Backgrounds, psychology, spending habits, behavioral quirks, technical literacy, and lifestyle.
They didn't just build a database of stats. They brought them to life.
The researchers dropped these billion persona agents into four distinct digital environments:
• Surveys
• AI chat interfaces
• Live web browsing
• Native desktop and mobile apps
Then they tested how this digital Earth reacted to real-world products, software updates, and pricing shifts.
The system recorded everything: how long an agent hesitated after a price increase, when they abandoned a broken checkout flow, and how much latency they would tolerate before closing an app.
When researchers tested persona adherence, the AI agents successfully maintained their assigned psychological and demographic behavior 91.5% of the time.
Think about what this means for the future of business.
You no longer have to wait weeks for a market research firm to tell you if a product feature will fail.
You can simulate how 8 billion different types of humans will react to it in real time, overnight, on a single server.
An average of 25 schools closed EVERY DAY in India over the past 10 years, while enrolment in government schools declined by 2.26 crore students.
"A total of 94,000 government schools have shut across the country over the last 10 years, according to a recent NITI Aayog report. The number of government schools declined from 11.07 lakh in 2014-15 to 10.13 lakh in 2024-25."
The number of government aided schools also dropped
One of India's achievements over the last few decades had been that nearly every child did enroll in schools. The learning outcomes were not optimal but that was a beginning.
Now while not improving on the outcomes...we are going backwards even in enrollments.
While the data was not segregated by gender, having or not having a neighborhood School is the biggest determinant of whether girls continue their education.
Let me repeat for the nth time: The most important investment a country can make is in its human capital which means investment in health and education... We are just not doing it!

An Open Letter to the Jantar Mantar protestors:
My dear young friends,
I address you today not as a politician or an MP, but as someone deeply troubled by what is happening to your generation of young Indians.
This is personal for me. I was born to a middle-class family: my father was a salaried newspaper employee, my mother a homemaker, with three children to educate on one income. For a family like ours, merit was not a slogan. Scholarships, fair examinations, honest results — these were the only way one salary could carry three children's dreams.
I went to school in Mumbai and Kolkata, to college here in Delhi, topped the University and earned admission into IIM — and chose instead to follow my passion for international affairs, in America, on a scholarship. Nothing was inherited; everything was earned by hard work and yes, Exams.
So I know that a fair, merit-based system is the only ladder for young people from lower and middle-income families to climb up. When that ladder is broken — papers leaked, examinations cancelled, trust destroyed — the children of the rich and powerful do not suffer. They have other ladders. It is your dreams, and your families' sacrifices (and tragically, in some homes, young lives themselves) that are betrayed.
To the young people gathered at Jantar Mantar, and those raising your voices peacefully across India: this country hears you. Your anger is not indiscipline — it is the anguish of a generation that did everything right and was still betrayed . You are not alone.
And to the millions of young Indians watching quietly: your generation is not a problem to be managed. You are the answer to India's future. Do not lose hope. This ladder will be rebuilt — by you, and by every Indian who stands with you.
To Shri Sonam Wangchuk-ji, my heartfelt appeal: please end your fast. You have awakened the conscience of the nation; that is what a fast is meant to do. India needs your voice for the long road ahead.
With Parliament in session again from Monday, we will have an opportunity to raise the students’ issues in the highest forum of our democracy. That’s where the problem should be addressed, not by fasting unto death. Please heed my plea.
And finally, to the Government: I respectfully urge you to reach out and engage in the dialogue our democracy owes its young citizens. That is not weakness; that is statesmanship.
@equitycaller Were you lucky enough to find a Gemini-type RM with any Indian bank? Kindly drop an appreciation post naming the bank and if possible, also the RM so we can all benefit.
Thanks Parimal @Fintech03 for recalling these historic battles.
As Chairman of @WIPO SCIT Committee, I remember emphasising to the assembly of 190 member states that knowledge generated by my ancestors in ‘laboratories of life’ has to be treated ON PAR with knowledge generated in ‘formal research laboratories’ of the west.
Traditional Knowledge was not considered as a knowledge at all in the International Patent Classification System till then, which was then was forced to change.
Please read and hear my first hand account of this battle in

Managed to get out of Dubai. The following is my personal opinion & experience 🇦🇪
Everything went quite seamless. Careem cabs operate normally. The airport is extremely well organized, considering the circumstances.
The world has changed since Saturday and unfortunately, the country I moved to 3 years ago has been under heavy attacks. Why? No one really knows.
However, I find it extremely disturbing that most media - including our beloved CT - exploits that serious situation to take cheap shots at Dubai and people who moved here.
There are real families and hard working people affected. Most are scared or feel extremely uncomfortable. It's a traumatizing experience to hear missile interceptions right above your house.
Nothing I wish for any human to ever experience, no matter if you pay 0% or 50% taxes. I don't even know what the link between those two things should be??
If anything, it proves that the UAE cares about their people and is able to protect its residents. Even at 0% income tax. Dubai was not known for it's strong military. It was always portrayed to be bling-bling golden steaks and influencers.
But the UAE has shown the entire world that it can defend 1,000+ drones and 200+ missiles from a direct neighbor.
That is impressive, whether you love or hate the UAE. Many countries would likely not be able to absorb that.
So, if anything: Dubai and the UAE have demonstrated that the system works.
I have lived in multiple countries around the world and the UAE is by far the most capable of handling crisis.
Why did I leave Dubai then? Because it's not a situation I want to be in. Missile interceptions and drone explosions are no joke.
Besides the danger that debris could hit your roof, there's an incredible intensity in the air. Most describe it as "intense calmness".
While the Government managed to keep everyone from panicking, it's impossible for everyone to stay fully calm. And you can feel that in the day to day.
The first night I got virtually no sleep. The night of my departure neither. I haven't left my house at all after the attacks started.
But I'm out now. I really hope that leaving the country wasn't necessary, and that I will be able to come back to Dubai as soon as possible.
And no, I'm not paid to say this, nor did I sign anything. Maybe part of the truth why no one who lives in Dubai has bad things to say about it is because it's one of the rare places on earth where people actually trust the Government and respect them?
Not only for creating wealth and understanding business, but for caring and communicating in a way most other countries are simply incapable of.
Anyways, I guess the point of this post is to
1) Tell everyone in Dubai that it's possible to leave right now. I know many people are very scared and want to get out. Be persistent with the airline if they cancel your flight and push hard to get rebooked on the next available one. And maybe choose a destination that isn't Europe, considering most of these flights are overbooked already and impossible to get on.
2) Dubai's self defense is impressive and we should acknowledge that. At least this one time, let's not derail into irrelevant discussions but show respect to the leaders + express empathy for those affected.
3) As an expat living in Dubai, I can still feel proud of my home country and do not have to choose. This isn't a black and white situation. Dubai is a melting pot of cultures and great place for Business. Other countries have better nature, social life or other things. It's also up to individual preference.
4) If you hate Dubai, yalla you don't need to live here, visit nor speak about it. Enjoy the place you live in and focus on your own. No need to feel triggered and take cheap shots at hard working people and families that are currently under heavy missile attacks.
One final thing that really became clear to me this week is that after all, safety, health and living in freedom are absolutely priceless.
May this all be over with soon and for sustaining peace to come in 🤲🏼

They really tried to say Dubai isn’t safe.
Meanwhile, the President of the State, His Highness Sheikh Mohammed bin Zayed Al Nahyan, is breaking his fast among his people in a public place, accompanied by His Highness Sheikh Hamdan bin Mohammed bin Rashid Al Maktoum, present, relaxed, and fully among the community.
At the same time, His Highness Sheikh Mansour bin Zayed Al Nahyan is in Abu Dhabi, having his post-fasting coffee in the open, as the city moves with its usual rhythm.
That is what real confidence looks like. That is what security feels like.
This is the U A E 🇦🇪
The uncomfortable truth isn’t that algorithms exist.
It’s that most people still think they’re playing a game.
This isn’t retail vs bots.
It’s participants vs observers.
The mistake isn’t being slower.
It’s broadcasting intent.
Every indicator, every “strategy,” every emotional entry is just telemetry.
Of course it gets harvested. That’s not sinister, it’s physics.
But here’s the part missing from this story:
Systems that optimize for harvesting yield cannot see outside the loop.
They front-run reaction, not conviction.
They arbitrage behavior, not understanding.
Copy-trading isn’t “being a shadow.”
It’s outsourcing thought to someone else’s incentive structure.
The real asymmetry isn’t speed.
It’s optionality.
Algorithms must act.
Humans can wait.
They’re locked into constant execution.
You can choose when not to play.
That’s the blind spot.
Not agriculture.
Not algorithm.
Sovereignty.
"Tamil Nadu, India’s top performing state last year, has far fewer very poor people than Gujarat, even though its GDP per person is similar. Part of the reason the state has excelled in providing public goods, even as Gujarat—and much of India—focuses on hard infrastructure, is that Tamil Nadu started social reforms a century ago. Another reason that Tamil Nadu has won so much electronics manufacturing is that it offers a well-educated female workforce. About 40% of all the women who work in manufacturing in India are employed in Tamil Nadu.
All across India politicians find it easier and more appealing to seek growth by laying concrete than by pumping up skills. New roads and bridges make for good front pages and bring immediate benefits. The fruits from improving schooling, by contrast, come much slower. Yet unleashing the power of India’s young and massive population will require investment in health and education. It will also mean fighting obstacles, such as sexism, caste and environmental degradation that keep people from fulfilling their potential. This is far from easy work. But, as Tamil Nadu shows, it would pay off in spades".
I see all these people saying IEA has turned a corner on oil demand with their forecast that oil demand will continue to 2050 (I would argue longer but that is a discussion for another day), good on IEA for finally admitting this.
Yet every MSM has grabbed onto this headline: IEA foresees massive oversupply on the oil market.
I ask you: With shale wells now producing more water than oil or gas, OPEC+ spare capacity now normalized, Bakken (second largest basin) showing notable declines in production, oil majors laying off staff, major auto companies moving from EVs to BEVs, AND electricity demand in set to increase 20 fold in the next 5 years due to AI...do you really want to short energy here?
