13 major companies have been caught red-handed with AI disasters since 2023.

They've paid millions in penalties and settlements.

But the media won't touch it.

Here's the disturbing pattern Big Tech doesn't want you to see: 🧵 Image Samsung. Deloitte. Workday. Air Canada.

These aren't startups making rookie mistakes.

These are Fortune 500 companies bleeding millions from AI failures.

And the disasters are accelerating... Image

Dr. Matthew Walker just went viral for exposing the truth about sleep science.

And he's NOT just talking about getting 8 hours.

He revealed genetic short sleepers, why your magnesium is useless, and the first sleep drug he actually recommends...

Here's what you missed: 🧵 Image 1/ The Magnesium Myth

Most forms of magnesium (oxide, citrate) don't cross the blood-brain barrier.

And sleep is produced by your brain.

Walker's verdict? "All you're doing is creating expensive urine."

Only magnesium L-threonate shows evidence—and only if you're deficient.

BREAKING: Salesforce's $200B company ran a 9-month AI experiment.

They gave AI agents access to their entire customer support, engineering, and sales.

Result: 1 million conversations. 360,000 hours saved.

But what Marc Benioff admitted on camera changed everything:

THREAD🧵 Image Marc Benioff promised 1 billion AI agents by year-end at Dreamforce.

Inside Salesforce right now: AI does 30-50% of work in engineering and support. 1,000+ jobs cut. No more coders hired.

This isn't a pilot. It's workforce replacement at scale.

Harvard just proved bedroom temperature controls sleep quality.

Participants fell asleep in 6.2 minutes when cool vs 20 minutes when warm.

Yet most people still don't optimize this simple factor.

Here's the exact temperature range that triggers deep, restful sleep: 🧵 Image Your core body temperature is the key.

When it drops by just 1°F, your brain floods with melatonin and initiates deep, restorative sleep.

Harvard researchers stumbled upon this when they noticed something strange...

Elon Musk's new interview with Joe Rogan just went viral.

And he's NOT just talking about SpaceX or Tesla.

Instead, he revealed what terrifies him most about AI... and it's not the technology itself.

Here are 8 shocking insights from their 3-hour conversation: 🧵 Image 1/ Instilling The Right Values In AI

@elonmusk's biggest fear isn't AI becoming too powerful. It's forcing AI to believe things that are false.

"If you tell AI that diversity is most important and misgendering is worse than nuclear war... you get very dystopian outcomes."

This is Satchin Panda.

He's a biology professor who's studied circadian rhythms for 20+ years.

His message? Your body has an internal clock—and ignoring it causes diabetes, weight gain, and early aging.

Here are 6 timing tricks to sync your circadian rhythm: 🧵 Image Panda is a professor at the Salk Institute in California.

In 2002, he co-discovered melanopsin, a blue-light sensing protein in your eyes that controls your master biological clock.

This discovery was named one of Science magazine's top 10 breakthroughs.

This is Andrej Karpathy.

Former Tesla AI Director who built their self-driving system from scratch.

He just spent 3 hours with Dwarkesh Patel revealing mind-blowing truths about AI that 99% of people wouldn't know...

Here are 9 insights that will change how you think about AI: Image 1/ Why It's The Decade of Agents (Not The Year)

Karpathy's reaction to AI hype: "We'll be working with these things for a decade."

Current agents lack intelligence, multimodality, and continual learning.

"They're cognitively lacking and it's just not working."

BREAKING: Google paid out $430K to researchers finding AI vulnerabilities & one pattern kept repeating.

Every AI system they tested had the same critical weakness. And attackers already know what it is.

Here's what they found:

(hint: it's not the technology that's broken) Image The AI security war is already here.

Cybercriminals are using AI to launch attacks 40% faster than before. 85% of all cyberattacks now leverage artificial intelligence.

But defenders are losing—and not for the reasons you'd expect. Image

Gratitude is one of the most ignored natural remedies on Earth.

Used right, it decreases depression symptoms by 35%, decreases stress, and improves sleep.

So, I started researching the science behind it...

What I discovered will blow your mind: 🧵 Image Most people think gratitude is just being "nice" or "positive."

But here's the science: Gratitude practice activates neural circuits linked to reward and trust, releasing dopamine and oxytocin.

These neurochemical shifts improve mood, reduce stress, and strengthen social bonds.

Here's what the data revealed:

(hint: the pattern matches every major technology bubble we've seen) Image The research findings are stark.

Despite $30-40 billion in enterprise AI investment, only 5% of companies are extracting millions in value.

The remaining 95% show no measurable P&L impact.

MIT's analysis reveals why this divide exists... Image
