@elonmusk So we can all be hunting for parts when you discontinue? 🤔

🚨 Do you understand what happened in the last 12 hours?

> A CEO of a $200 billion company said on camera that 35% of new grads won't find jobs. He didn't even flinch saying it.

> Meta made $165 billion last year and is still firing 15,000 people because apparently record profit isn't profitable enough.

> Some random guy in Florida sold his entire house in 5 days using ChatGPT. No real estate agent, no commission, no experience. Just vibes and a $20 subscription.

> A man in Australia cured his dying dog's cancer with AI after every single vet told him there was nothing left to do. Built a custom vaccine from his couch.

> The guy who created Uber and left 300,000 taxi drivers broke is back. Building robots now because apparently ruining one industry wasn't enough.

> Tinder wants access to your camera roll. Your drunk photos, your 3am notes app meltdowns, your deleted selfies. They're calling it a "vibe check."

> Naval, the man who made hundreds of millions investing in software, just said software is dead. Four words and the entire industry felt it.

> And Anthropic removed the limit on how long their AI can think and then doubled everyone's usage for free. Because when the product is addictive enough you give the first taste away.

All of that happened today. Not this week, not this quarter. Today. A random Saturday in March.

This is worse than you being on meth.

Amazon just confirmed 16,000 layoffs but sources inside are telling me the real story is so much worse

Word from three different VPs: the 16K number is just "Phase One" - internal docs show another 14,000 cuts planned for Q2

A director in AWS walked me through their new "efficiency matrix" - entire teams being replaced by 2-3 senior engineers running Claude Sonnet workflows

The Alexa division got completely hollowed out. 847 engineers two months ago. 23 remaining after this week. All hardware development moved to a Bangalore team of 31 contractors with Cursor access

Here's the sick part: they're making the outgoing engineers document their entire decision-making process into "knowledge transfer sessions" that are being recorded and fed directly into training datasets

One L7 told me he spent his final two weeks creating detailed prompt libraries and workflow documentation. Thought he was being helpful for the transition

Turns out he was literally training the AI agent that replaced his entire org

The contractors offshore are using his exact prompts and shipping features 40% faster than his old team of 12 Americans ever did

Internal Slack shows leadership celebrating "operational excellence" while badges get deactivated in real-time

They're calling it "right-sizing for the AI era" in the all-hands

But the P&L sheets I'm seeing show $280M in salary savings this quarter alone

The knowledge extraction is complete

If you're still at Amazon and haven't started job hunting, you're already dead

last week we got 1M views and 100s of death threats for giving Openclaw access to drones, humanoids, quadrupeds, and other physical hardware.

Now we’re releasing EVERYTHING open-source.

Dimensional gives agents access to the physical world. Join us.

🚨 BREAKING: Someone built a swarm of thousands of AI agents with real memories and personalities and used it to predict the future.

MiroFish is a universal swarm intelligence engine. And the live demos are scarily accurate.

Here is what it actually does:

→ Spins up thousands of autonomous agents simultaneously
→ Each agent has its own memory, personality, and behavior
→ Feeds on real-world data powered by GraphRAG
→ Predicts markets, public opinion, and narrative outcomes
→ Simulates how crowds think before it happens

The live demos are what got people. Scarily accurate is the phrase everyone keeps using.

17,300 stars. +2,907 in a single day.

It's 100% free and open source.

@michaelandregg @FlyWireNews @Philip_Shiu Why couldn't this scale up to a human brain?

[Michael Andregg @michaelandregg]

We've uploaded a fruit fly. We took the @FlyWireNews connectome of the fruit fly brain, applied a simple neuron model (@Philip_Shiu Nature 2024) and used it to control a MuJoCo physics-simulated body, closing the loop from neural activation to action.

A few things I want to say about what this means and where we're going at @eonsys. 🧵

[Josh Kale @JoshKale]

Scientists just copied a Fruit Fly's biological brain and trapped it inside of a computer.
Not an AI model trained to act like a fly... A total digital copy of a fly !! This is some sick sci-fi stuff:

- They scanned and copied the brain, neuron by neuron, synapse by synapse, from electron microscopy data.
- Then dropped that brain into a simulated body in a video game like environment.

The fly walked. It groomed. It fed. Nobody taught it anything. The behavior was already in the wiring.

The entire premise of modern AI is that intelligence is something you train into a system. This is proof it's something you can transfer out of one. Wild times
