He predicted:

• AI vision breakthrough (1989)
• Neural network comeback (2006)
• Self-supervised learning revolution (2016)

Now Yann LeCun's 5 new predictions just convinced Zuckerberg to redirect Meta's entire $20B AI budget.

Here's what you should know (& how to prepare): Image
@ylecun is Meta's Chief AI Scientist and Turing Award winner.

For 35 years, he's been right about every major AI breakthrough when everyone else was wrong.

He championed neural networks during the "AI winter."

But his new predictions are his boldest yet...
1. "Nobody in their right mind will use autoregressive LLMs a few years from now."

The technology powering ChatGPT and GPT-4? Dead within years.

The problem isn't fixable with more data or compute. It's architectural.

Here's where it gets interesting...
Every token an LLM generates compounds tiny errors exponentially.

The longer the output, the higher the probability of hallucination.

This is why ChatGPT makes up facts. Why scaling won't save current models.

Mathematical certainty.

But LeCun didn't stop there:
2. Video-based AI will make text training primitive

LeCun's calculation: A 4-year-old processes 10¹⁴ bytes through vision alone.

That equals ALL the text used to train GPT-4.

In 4 years. Through one sense.

This changes everything about how AI should learn:
Babies learn gravity and physics by 9 months. Before they speak.

"We're never going to get human-level AI unless systems learn by observing the world."

Companies building video-first AI will leapfrog text-based systems.

Here's what Meta is secretly building:
3. Proprietary AI models will "disappear"

LeCun's exact words: "Proprietary platforms, I think, are going to disappear."

He calls it "completely inevitable."

OpenAI's closed approach? Google's secret models? All doomed.

His reasoning will shock the industry:
"Foundation models will be open source and trained in a distributed fashion."

A few companies controlling our digital lives? "Not good for democracy or anything else."

Progress is faster in the open. The world will demand diversity and control.

LeCun's timeline will surprise you:
4. AGI timeline is 2027-2034

@ylecun's exact words: "3-5 years to get world models working. Then scaling until human-level AI... within a decade or so."

But it won't come from scaling LLMs.
Every company betting only on GPT-style scaling will be blindsided.

LeCun calls the "country of geniuses in a data center" idea "complete nonsense."

The smart money is repositioning for the architecture shift.
5. AI assistants replace all digital interfaces

Ray-Ban Meta glasses: Look at Polish menu, get translation. Ask about plants, get species ID.

That's primitive compared to what's coming.

AI will mediate ALL digital interactions.

Here's what this means for your business:
The economic implications are massive.

Companies building on OpenAI APIs could see foundations crumble in 3-5 years.

But early movers positioning for JEPA? They'll capture the next $10 trillion wave.

LeCun's advice for surviving this transition:
How to prepare:

Researchers: "Don't work on LLMs. Focus on world models and sensory learning."

Companies: Build on open-source foundations like PyTorch and Llama.

When the shift happens, you adapt instantly.

The window to position yourself is closing: Image
LeCun's warning reveals the hidden opportunity:

As companies abandon LLMs for world models, they're creating a massive validation gap.

These new architectures aren't just different - they're fundamentally harder to monitor and govern.
While everyone's racing to build next-generation AI, the smart money is positioning for what makes them trustworthy.

The companies that survive this transition won't just have better models.

They'll have the governance frameworks to validate them at scale.
In a world where AI shapes every business decision, trust isn't optional.

It's the only competitive advantage that matters.

And there's one thing that builds AI trust faster than anything else:
Proper model validation and governance.

Columbia and NYU researchers tracked 11,000 people for 20 years.

Urine tests before. Urine tests after.

When they switched to clean water, their risk of dying from cancer and heart disease dropped 50%.

Here's what was in their water the entire time: 🧵 Image
Image
The study was run by Columbia University in Araihazar, Bangladesh.

622 adults. All drinking from wells above the arsenic safety limit.

Each was given a water filter.

Researchers tracked urinary arsenic, a direct biomarker of what's inside your body. Image
Within a single week, median urinary arsenic dropped from 117 µg/L to 51 µg/L.

A 56% reduction in the toxin load inside their body.

From one change. In 7 days.

But the real question was: does that actually change health outcomes? Image

Harvard researchers put 24 office workers in the same room for 6 days.

They changed one thing about the air. The workers didn't know.

Then they tested their brains.

Cognitive scores doubled.

Here's what the air you're breathing right now is doing to your brain: Image
Harvard's T.H. Chan School of Public Health. 2016.

24 participants. Full work days. 9 to 5.

An environmentally controlled office space.

Blinded to every condition.

No one knew what was changing. Image
On different days, the researchers changed the air.

Conventional office air. Then "Green" air with low VOCs. Then "Green+" air with doubled ventilation.

Same room. Same people. Same tasks.

Only the air changed.

Thyroid cancer used to hit people in their 60s.

Now it's the #1 most common cancer in young adults aged 16-33.

According to the National Cancer Institute, diagnoses have tripled since the 1990s.

Here are 8 things destroying your thyroid without you realizing:

1. Tap water Image
Image
A 2024 meta-analysis found high fluoride in drinking water raises TSH, a marker of reduced thyroid function.

A UK study of 7,935 practices found nearly 2x the hypothyroidism rate in fluoridated regions.

But #2 is hiding in your fridge right now...
2. Soy products.

You drink soy milk thinking it's healthy.

A review of 14 trials found soy interferes with thyroid hormone absorption.

If your iodine is low, it suppresses the gland entirely.

And #3 is in almost every "healthy" kitchen...

Testosterone is more than a sex hormone.

It builds muscle, burns fat, and sharpens your focus.

But modern life is killing it... quietly and daily.

Here are 10 daily habits that naturally boost testosterone without pills🧵:

1. Lift heavy weights
Squats, deadlifts, and bench press trigger the largest acute testosterone spikes.

But here's what most people get wrong:

Lifting doesn't permanently raise resting T. It works indirectly by cutting fat and improving insulin sensitivity
2. Get 7-9 hours of quality sleep

Your body produces most of its testosterone during deep sleep.

A University of Chicago study found men sleeping only 5 hours had 10-15% lower T than those sleeping 8.

Poor sleep tanks your testosterone faster than almost anything.

We have proof that HEAT STRESS can reverse the brain's natural decline after 30.

A 20-year Finnish study found that one 20-minute habit activates BDNF, the "neurogenesis protein" that grows new brain cells, strengthens memory, and cut dementia risk by 66%.

Here's the breakdown: Image
Image
After age 30, your brain starts losing neurons every day.

Most people don't notice until it's too late.

Memory slips. Focus fades. Brain fog becomes "normal."

But it's not normal.

It's a sign that your BDNF levels are dropping. Image
Image
BDNF is the most important protein in your brain most people have never heard of.

It grows new neurons. Strengthens existing ones. Protects areas responsible for memory, learning, and mood.

Low BDNF is linked to Alzheimer's, depression, and chronic fatigue.

Big Pharma makes $26B/year on ADHD drugs alone.

Meanwhile, a treatment exists that retrains your brain's electrical patterns without a single pill.

It's been tested in 38 randomized trials.

The results are shocking, but not for the reason you think.

Here's what they found: 🧵 Image
Image
Your brain runs on 5 electrical frequencies:

• Delta (deep sleep)
• Theta (creativity, daydreaming)
• Alpha (calm focus)
• Beta (alertness, problem solving)
• Gamma (peak performance)

When these get out of balance, you get anxiety, ADHD, brain fog, and insomnia. Image
Neurofeedback measures your brainwaves in real time via EEG sensors.

When your brain hits the right pattern, you get a reward (a sound, a game responding).

When it drifts, the feedback stops.

Over time, your brain learns to self-regulate. No drugs needed. Image
