Your API keys might be able to withdraw. @krakenfx just went live in ChatGPT read-only: balances, no trades, no transfers. As @arjunsethi put it, if an agent can move your money, the question is what the key can't do. Check yours ↓

6.9M BTC have their keys showing. Brian Armstrong ranked quantum above AI as crypto's long-term threat and called it "a matter of when, not if." The 6.9M estimate traces back to @projecteleven. @coinbase is upgrading custody now. See if you're exposed ↓
Ensuring Bitcoin’s future in a post-quantum world requires preparation and collaboration across the industry. We're doing our best to contribute to that work along with many others. New blog post live. (link in follow on post).

He graded his own predictions, in public. In 2018, roboticist @rodneyabrooks wrote down dated calls on robotaxis, EVs and AI, then scored himself every year. 26 accurate, 6 too optimistic. Waymo came 8 years early, with humans in the loop. See his receipts ↓

30 days. For 33 years. Since 1993, @JensenHuang has told himself @Nvidia is 30 days from going out of business. He still felt it this year, with Nvidia making $215.9B. Sega, CUDA’s silence, a recession bet: all in his own words. Why the fear never left ↓

Why is upgrading Bitcoin for quantum so hard? The signatures get up to 123x bigger. Today's are 64 bytes. The post-quantum options run from 666 to 7,856, and every byte costs block space. Why picking one is the migration's hardest call ↓

99.9% sounds perfect. For a robot, it’s a mistake every day. Surgery needs 99.999%. Driving needs 99.9999%. That gap is called the 99.9% wall, and @RoboStrategy’s data shows how far each job still has to climb. See which jobs robots can take first ↓

Enigma had 103 sextillion settings. It still fell to a machine built to break it. Bitcoin's signatures are next in line. The estimate of qubits needed fell from 13 million to under 500,000 in four years, and Bitcoin still hasn't picked its fix. Where the race stands ↓

AI read 100,000 years of human writing. Robots have about one year of data. That gap is why there are rooms full of people in VR headsets right now, and why millions are filming their own hands doing chores. 60 seconds on the data wall in robotics ↓

Privacy you don’t have to ask for. @0xMiden’s partner mainnet is live, and I tested it on @joinbread on day one with real money. Every payment is private by default. No settings, no extra steps. Thanks to @azeemk for the invite. My first look at private payments ↓

Headlines tell you what happened. A percentage tells you what people expect next. In 2024, poll-based forecasts called the election a coin flip. Polymarket had Trump at 60%+ for weeks. 40 seconds on reading prediction markets as a news feed, and where they get it wrong ↓

How many qubits does it take to break Bitcoin? Depends which kind you count. Error correction groups noisy physical qubits into far fewer reliable logical ones. Under 500,000 physical could mean about 1,200 that actually compute. The number worth watching ↓

The hottest job in robotics might be wiping a table on camera. Chatbots learned from the internet. Robots have nothing like it, so companies pay people to record chores. @GeneralistAI raised $400M chasing 500,000 hours. Watch the data gap drawn to scale ↓

Someone could be recording your encrypted traffic. Not to read today. To read later. The web is quietly swapping its locks. ~70% of browser traffic to @Cloudflare is now post-quantum encrypted, up from ~2% in early 2024. Watch the jump from 2% to 70% ↓

No AI-designed drug has been fully approved. Yet. Insilico’s AI found a target for a lung disease in 2019 and helped design a drug for it. Now it’s in a 320-patient Phase III trial. Watch years of drug development shrink on the timeline ↓

A humanoid robot rang the closing bell at Nasdaq. @Rewkang said it best: “AI has lived mostly on our screens.” Not anymore. Massive day for @RoboStrategy, @intern and the whole team, so I gave it the cut it deserved. The moment that started it ↓

Someone won a full bitcoin for cracking a crypto key on a real quantum computer. The key was 15 bits. The record before it was 6. A Bitcoin key is 256. @projecteleven Q-Day Prize is the clearest scoreboard we have for quantum risk. See how small 15 looks next to 256 ↓

In 1979, Three Mile Island became shorthand for nuclear fear. Now a reactor at that same site is coming back, and the buyer is Microsoft. Big Tech has committed nearly 10 GW to nuclear for AI. (Voice: ElevenLabs) Watch the glow come back on ↓

Everyone’s asking when crypto goes mainstream. I think it already has. You just can’t see it. Cards settling in stablecoins. Agents paying inside web requests. Treasuries living onchain. None of those people opened a crypto app. Watch where the crypto is hiding ↓

AI is running out of room down here. So some companies are looking up. A startup trained an AI model in orbit. Google sent four AI chips up on Oct 1. The catch: launch needs to hit ~$200/kg. (Voice: ElevenLabs) See what it would take ↓
