LinkedIn is going to be *pissed* when they find out about Fable next week

Slow clap for all the people in India who explained to the rest of the gullible masses that tech sovereignty is not necessary. That India should remain an eternal customer.

[Elder Moraes @elderjava]

Recently there was a decision in the @java world that left a lot of people unhappy. The #OpenJDK maintainers decided they will not accept contributions of AI-generated code. Before we react to it, let’s understand what’s actually going on.

Sir, they have blocked access to the very AI models you said we should share instead of build

A short history of how we got here, because the chronology is the whole story.

January: the Pentagon demands unrestricted use of Claude for autonomous weapons and domestic surveillance. Anthropic says no.

February: the President orders every federal agency to drop Anthropic. The Defense Secretary bans Pentagon contractors from doing business with them. A rival announces its classified-network deal within hours.

March: the Pentagon designates an American company a "supply chain risk" under a statute written for foreign adversaries. A federal judge blocks it.

May: the Pentagon signs AI deals with seven companies. Anthropic is not one of them.

June 9: Anthropic releases Fable 5.

June 12: Commerce issues an export control directive over a jailbreak that, by the government's own account, was demonstrated verbally, came with no written explanation, and involves a capability you can get from other publicly available models today.

Two things are true at once.

First: Anthropic spent months marketing Mythos as too dangerous to release. Sam Altman said it was "incredible marketing to say we have built a bomb." The Commerce Department has now formally agreed it is a bomb. If you describe your product as a munition in every press release, eventually a government takes you at your word. They wrote the legal predicate themselves and called it a brand.

Second: we have run this experiment before. In the 90s the government classified encryption as a munition under ITAR. Activists defeated it by printing PGP's source code as a book, because books are protected speech and floppy disks were arms exports. A t-shirt with three lines of RSA Perl was legally a munition. The controls collapsed because math does not stop at customs.

The new wrinkle is the "deemed export" rule: showing controlled technology to a foreign national inside the US counts as exporting it abroad. Which is why Anthropic's own foreign-national employees are now locked out of the model they built. The munition is in the building and the people who made it are not allowed to look at it.

The jailbreak is the paperwork. The refusal was in January.

According to Grok, Andrej Karpathy is an EB-1 extraordinary ability green card recipient, not a US citizen. Thus under these new restrictions he is not permitted to use, or work on, Mythos 5 or Fable 5 as of 5:21pm tonight.

Vibe coding with AI is fun...

Until a critical bug hits production at 3 AM and you realize you have zero idea how your own codebase actually works.

How are you guys maintaining this AI-generated spaghetti long term?

[Péter Szilágyi @peter_szilagyi]

The scary part about Anthorpic's Fable nerf is not that it refuses to answer biology or cryptography. It's that it foreshadows what's coming. A world where a couple companies decide what you can and cannot do. They're building a new ruling class and you're not in it...

[Pushkar N Kulkarni @pushkar_nk]

Exactly my feelings after working with Fable. I felt vulnerable for the first time!

[staysaasy @staysaasy]

I’m 24 hours in on Fable and I just sold everything I have but my SPV shares of Anthropic.

When people say AI is going exponential this is what they mean. We are in the singularity. I can feel the G forces accelerating.

Every single thing I asked it, it got right.

The safeguards are truly needed. Without it I believe we’d be living in a Mad Max style apocalypse in the near future.

I’m afraid to open my phone and see what else has happened every hour that ticks by and people have this model. The world as we know it is over.

I don’t know where to go from here. I don’t know what purpose humans could possibly have when we’re now closer to animals than we are to the most intelligent thing in the universe.

Existential doesn’t even describe it. I walked the streets of NYC yesterday like the scene in the terminator before the nukes went off.

Stay safe everyone.

The refactor completed in 15 min using 65k tokens. I need half a day to review the changes!

[Pushkar N Kulkarni @pushkar_nk]

Asked Fable to do a DRY refactor involving 5 repositories. Let's see how it goes!

Once the bubble pops, Anthropic and OpenAI will become the Coinbase and Block of the AI world. Mundane companies that ship narrative wrappers on mundane bytes.

That the bubble will pop isn’t some apocalyptic doomsday prophecy. It’s not that complicated: AI is freakishly expensive to serve. If the returns on the other end are not justified, the bubble pops. And thus begins the decades long buildout to actually economically justifiable AI.

It’s amusing how resistant reality is to our fictions and fantasies. In the peak of the crypto bubble we thought reality was going to be transformed into financial liberty and democratization for all, and network states and decentralized reserve currencies. Coinbase stood to be a multi-trillion dollar company and is now just a mundane tech startup.

Today we spin similar narratives about the intellectual upheaval of AI, about the new democratization of intelligence and how everything will soon begin to orbit this new technology.

At the end, Anthropic and OpenAI will be mundane IT providers with an insanely grim research outlook to make AI economically sensible and useful, no different from Google’s position in trying to make quantum commercially viable.

Reality is, fortunately, pretty hardened against our delusions.

A LINUX KERNEL DEVELOPER PROVED THE THING YOU PUSH CODE TO IS SECRETLY A DATABASE THAT CAN VERSION ALMOST ANYTHING AND THAT MOST DEVS HAVE ONLY EVER TOUCHED A TENTH OF IT

42 minutes from Josh Triplett -- a longtime Linux kernel and Debian developer -- showing that Git is a general-purpose, tamper-evident versioning engine that just happens to be famous for code.

-> The moment it clicks, Git stops being "Where my code lives" and becomes what it really is underneath: a content-addressable store that can version almost anything -- your configs, your notes, your servers' state, entire datasets.

People run whole wikis on it. They version their entire machine's configuration with it. They ship websites by pushing to it. They track data too big to email. None of it is a hack -- it's the same handful of objects you already use for code, pointed somewhere new.

Treating Git as a code-only tool was never the ceiling -> it's a versioning engine for anything, and the people who see that automate what the rest of the team still does by hand. And as AI agents start spitting out not just code but configs, docs and data, the one system that can version and audit all of it at once is already sitting on your machine.

You learned five commands to survive. This is the talk that shows you were standing on top of a database the whole time.

It changes what you think the tool is even for.

2 months ago, I wrote "The Harness Is Everything" 1.3M views.

Last week's Life-Harness paper: 116 of 126 model-environment setups improved by patching the harness alone.

Model frozen. 88.5% mean lift across 18 backbones.

Anthropic engineer:

"You can build 5 assistants in one afternoon. Each one handles a task you've been doing manually every single day."

In 45 minutes he builds 5 focused agents from scratch on camera.

Most people are still doing code review, testing, and documentation by hand every single day
