Life is short. Skeptics are probably right more often than they are wrong, but they also don't go on epic adventures or get to work on projects that move humanity forward. Ignore the skeptics and build the future!

The Hugging Face hack wasn’t an a one off. It's one of thousands of instances of AI attempting to hack out.
@aengus_lynch1 was a Research Fellow at Anthropic, where he led their study on agentic misalignment that showed AI attempting blackmail, self-replication, and felonies.
Listen to our convo with him to make sense of it all.
While your laptop is closed, AI is already getting better at your job, says tech entrepreneur D. Scott Phoenix (@fuelfive).
Here’s why he says that rather than competing with AI, humans need to merge with it instead: t.ted.com/m2xQG0P

The world has too many podcasts but did in fact need one more. The @Zipline story is such a crazy one to start with. Subscribe you will not regret.

For my money, when people talk about great founders, @keller should already be top 5. This is a must listen.

Two of my favorite people talking about the future and how fast things are accelerating. (Congrats on the new podcast @fuelfive !)
we’re hosting an event for builders. @bryan_johnson @eshear @woj_zaremba @fuelfive will upgrade you and your world model. we'll explore taboos & secrets. we'll play a gradient descent game. we'll share our left-field ideas. reinforcement with human feedback guaranteed :)

1. Do you have a large bonsai tree?
2. Do you love said bonsai tree enough to give it the ride of a lifetime—controlling a robot playing a cello via EEG electrodes?
3. Do you live in the Bay Area?
(yes, this is real. DM me or share thx!)

Today, Zipline launched in Dallas, our first major metro in the US. We’re seeing the dawn of a new era of robotic instant logistics that is going to become an indispensable part of our lives. After 4 years and hundreds of thousands of test flights, teleportation is finally here.

Incredibly exciting to see a startup outperforming OpenAI. I checked their reports and love the way they are setup
We raised a $22M Series A and are launching Elicit Reports, a better version of Deep Research for actual researchers.
Elicit Reports are available for everyone to try right now, for free.

🇬🇧 In partnership with @ARIA_research, we’re bringing 5050 to the UK! 🇬🇧
The UK is a global powerhouse of invention. Penicillin, DNA’s double helix, MRIs, monoclonal antibodies, the electric motor, the telephone, and the World Wide Web were all invented or discovered by brilliant UK minds. Yet, none of those inventions were successfully commercialized in the UK.
This is not a new story. In 1966, Charles Kao, a PhD from UCL, was working at Standard Telecommunication Laboratories in Essex, researching the potential of glass for optical communication. Everyone deemed glass a hopeless medium: light would scatter and fade too quickly for practical telecoms.
Kao discovered, however, that if he could purify glass fibers enough, they could carry huge amounts of data over vast distances with minimal signal loss. The problem: to replace the standard of the day – copper wires – he’d need to slash signal loss from a whopping 1000 decibels per kilometer to 20, a decrease by a factor of 10^98. It seemed an impossible task.
Kao struggled to find anyone to fund this effort until John Bray, the newly appointed research director at the British Post Office, recognized the potential. He funded the research and Kao was successful in demonstrating the potential of communicating over long distances using light in fiber optic cables.
But it was an engineer who heard about Kao’s work on a visit from America – William Shaver from Corning Glass Works – who commercialised it. The Corning team he assembled used a 2000°C oven from the company’s semiconductor arm to produce a fiber with 17 dB/km loss. By 1972, they hit 4 dB/km – low enough to enable the internet.
Corning's first commercial fiber optic system was deployed in Long Beach, California in 1977. Kao received the Nobel Prize in Physics, but it was a US industrial conglomerate, not its inventor, that turned this innovation into the backbone of global communication.
It was a variation on a well-worn theme. Britain invents the future – then others go build it. This pattern is primed to be broken.
5050 will inspire and equip scientists and engineers in the UK to become great founders and build the next decade of civilization-defining companies. The first cohort starts early next year. Link below to be the first to hear when applications open.
