Godfather of AI: "If you sleep well tonight, you may not have understood this lecture."
This 47-minute lecture is the best thing I've seen about AI in the last few months.
Hinton built the neural networks behind every AI alive, then quit Google to warn us it's already ahead of us on most cognitive tasks.
Despite that, most people open Claude, type one thing, close the tab and think they're using AI, but they're using maybe 10%.
I turned his talk into 17 Claude features 99% of users never find.
Watch the lecture, then read the article below.
Andrew Ng just revealed why the AI companies throwing the most compute at the problem are going to lose.
The winner of the intelligence race won’t use the most compute.
They’ll waste the least.
Ng: “Most of your high-dimensional data lies on a lower-dimensional subspace. It’s just a fact of life.”
Here’s what that means in practice.
You have a 10,000-dimensional dataset.
Every dimension dragged through every calculation.
Every training cycle hauling dead weight the model will never use.
Ng: “You’re carrying around these 10,000-dimensional examples throughout your whole training process.”
That bloat isn’t just inefficient.
It’s a tax on every computation you run.
Memory bandwidth. Network bandwidth. Computational speed.
All of it eaten by dimensions that contribute nothing to intelligence.
They contribute noise.
The insight that separates the architects from the arms race: that 10,000-dimensional dataset is almost entirely captured by a much smaller subspace.
The signal lives in a fraction of the space you’re paying to process.
Compress it. 10,000 dimensions down to 1,000.
Ng: “You can run your learning algorithm on a much lower-dimensional set of data and it may be much more efficient.”
Same hardware. Same budget. A fraction of the friction.
Brute force is the strategy of whoever has the deepest pockets.
Compression is the strategy of whoever actually understands the problem.
The companies that master this don’t just build faster models.
They build models that find more truth in less data than anything scaling blindly ever will.
Intelligence was never about processing everything.
It’s about knowing what to cut.
We’re excited to launch the Codex app, a command center for building with agents.
It gives you a focused space to manage multiple agents at once, run work in parallel, and collaborate with agents over long-running tasks.

I think many in India are living in a make-believe dream world.
The moment I nudge them to wake up, they start abusing me for disturbing the dream - despite the garbage, stench, poverty, pollution, unhappiness, unemployment, traffic, corruption, and more.
To
Shri Narendra Modi
Hon’ble Prime Minister of India
South Block,
New Delhi – 110011
Subject: Urgent Appeal for Action Against Rising Racism and Communal Violence in India
Dear Hon’ble Prime Minister,
I am writing to you not only as an Indian born on Indian soil, but as someone who has proudly represented India across the world for more than three decades. It pains me deeply to write this letter, but my conscience leaves me no choice.
A 24-year-old MBA student from Tripura, Anjel Chakma, lost his life in Dehradun after a brutal assault that reportedly followed a racially motivated altercation. This young man - full of dreams, potential, and hope - succumbed to injuries inflicted solely because he looked different.
Prime Minister, this is not just a crime.
This is a tragedy for India’s soul.
For decades, millions of our fellow Indians from the North-East have faced stereotyping, humiliation, and racism in their own country. They are 100% Indian - in identity, history, and sentiment. Yet they often walk through our cities with the fear of being mocked, targeted, or worse. Anjel’s death is not an isolated incident; it is a reflection of a deeper social problem that requires immediate national attention.
But this tragedy does not stand alone.
In recent months, India has witnessed a sharp rise in violence against Dalits, Muslims, and Christians - communities that have long contributed to the fabric of our nation. Reports of killings, assaults, and targeted intimidation have become disturbingly frequent. Regardless of who the victims are, hate-driven violence is an assault on the very idea of India.
Whether the victim is from the North-East, a Dalit, a Muslim, a Christian, or any other community, the message must be loud and clear:
Communal hatred is wrong. Racism is wrong. Targeting people because of their identity is wrong. And it must stop.
India is home to 1.4 billion people who look different, speak different languages, pray in different ways, and follow diverse cultural practices. And yet, for 76 years, we have shared one national identity - Indian.
If our diversity becomes a trigger for violence, we lose the essence of who we are.
I respectfully urge you to consider the following urgent actions:
1. Make an unequivocal national declaration condemning racism and communal violence.
Your voice can set the tone of the nation and reassure communities living in fear.
2. Direct a transparent, time-bound investigation into the death of Anjel Chakma.
His family - and our nation - deserve justice.
3. Initiate a national program to address racism and inter-community hatred.
Sensitization in schools, colleges, workplaces, and public institutions is long overdue.
4. Strengthen legal protections against hate crimes, racism, and targeted violence.
India must demonstrate that it values every citizen equally.
Prime Minister, no parent in India - whether in Tripura, Uttar Pradesh, Kerala, or Nagaland - should fear for their child’s life because of their identity. Not in 2026. Not in a nation that aspires to global leadership.
As someone who has spent his life building technology that connects people, I cannot remain silent when our own society risks becoming disconnected from compassion, respect, and unity.
I sincerely hope that under your leadership, India will confront this issue with honesty and courage, so that Anjel Chakma’s death becomes a turning point - a moment when the nation chose unity over prejudice, justice over silence, and humanity over hate.
With respect,
Sabeer Bhatia

Missed manufacturing. Losing AI. 300M youth with obsolete education.
My playbook: Open India to foreign companies - no forced local partners. 10-year tax holidays linked to jobs. Massive investment in critical thinking. Decentralize governance. Central planning is a dead end.
Declare India “Open to Work.”
I was inspired by this so I wanted to see if Claude Code can get into my Lutron home automation system.
- it found my Lutron controllers on the local wifi network
- checked for open ports, connected, got some metadata and identified the devices and their firmware
- searched the internet, found the pdf for my system
- instructed me on what button to press to pair and get the certificates
- it connected to the system and found all the home devices (lights, shades, HVAC temperature control, motion sensors etc.)
- it turned on and off my kitchen lights to check that things are working (lol!)
I am now vibe coding the home automation master command center, the potential is 🔥.And I'm throwing away the crappy, janky, slow Lutron iOS app I've been using so far. Insanely fun :D :D
“You’re not an Indian citizen, you have no right to comment on India.”
Nonsense. I was born on Indian soil and have a God-given right to speak about my country of birth. Reject those who try to silence debate - they fear truth.
