Truth is Expensive: Why RAG is Doomed and What Actually Matters You're not building a truth machine. You're building the world's most efficient fiction amplifier. That's not a bug. It's the inevitable result of solving the wrong problem. Yuval Noah Harari's core insight—delivered in his latest book Nexus and his viral TED thesis—is brutally simple: Humans are a post-truth species. We didn't conquer the planet by being right. We conquered it by believing in shared fictions: gods, nations, money, brands. These stories don't need to be true. They need to be believed. [1] And now we're hardcoding that vulnerability into AI.

Got online to dozens of emails from builders and investors on my Opensource AI Must Win declaration Apparently someone posted it on HN yesterday and it was the 2nd highest voted of the day Over the next few weeks I will be in discussions with researchers, investors, and others to ensure we bring that vision to life More soon

There is no inevitability in AI. We all have agency in what comes next: Path 1: closed-source APIs, concentration of power, and a future decided by a handful of people in Silicon Valley and DC Path 2: open-source AI, where everyone gets to participate, own, and build together, including orgs like the city of Rio. Pick your path anon!

I'll be the first to say it: Dario needs to be ejected from Anthropic. He and his gang of Effective Altruists have spent years spreading fear, uncertainty, and doubt. The oldest trick in the book: FUD. Now Anthropic is paying the price, and Dario needs to take responsibility for this debacle.

Fuck you, @AnthropicAI, you guys are evil and malicious and you know exactly what you're doing to secure your moat through regulatory capture

1. Spread false existential fear. 2. Put the thing online nonetheless. 3. Wait for the dumb government officials to react. 4. Profit.

This is your wakeup call. Anthropic just took down Fable 5. It's over. Here's the thing tho: no company or government will EVER be able to take away your local models. There are Opus level models you can run right now on your home GPUs, and nobody can ever stop you from using them This is only the beginning of events like this. Day 1. More government overreach will happen. This will only keep happening more and more as models get closer to AGI Become sovereign. Buy your own compute. Before even that becomes illegal

self-inflicted. this would have NEVER happened if anthropic didn't make such a big deal about mythos being dangerous.

Decided to go to DC next week to talk directly with policymakers. Not sure how impactful it will be but with everything happening, feels like a good time to share more about open-source AI, transparency, concentration of power, the real risks vs the real benefits. Who do you think I should meet there (Congress members, WH people, public orgs,...)?

He fear mongered the United States government to steal Claude from him EA’s are their own worst enemy, aren’t they?

great fucking job, Anthropic incredible fear-mongering fuck progress, fuck science, fuck technology fuck the whole world except for US let's all go to the stone age together

The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees. The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance. Access to all other Claude models is not affected. We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible. Read our full statement: anthropic.com/news/fable-myt…

This is true. I spent most of my life trying to solve diseases & help humanity. Now I am banned by Fable 5 because of that-can’t even say "human" as a biomedical scientist! Incognito mode works fine. I am protesting @AnthropicAI in the strongest possible way. Shame on you people!

You guys don’t really understand how bad and malicious Anthropic is Once called Misanthropic by @elonmusk, and for a reason Necessary read to fight back against evil

To everyone defending Anthropic by mentioning how things are against their ToS: Cry me a river they trained their models on the entirety of humanity's knowledge

Wrote an article on the case against Anthropic as a safety-branded permission regime for Cognition Infrastructure Covers sabotage-as-safety, anti-Opensource rules, Fable, regulatory capture, data asymmetry, Claude Code, and Who Owns Intelligence Must read, bookmark it for later

The release of Anthropic's Mythos-class Claude Fable 5 is the latest signal that we are in a phase of exponential growth in AI capabilities, "takeoff mode". The biggest leaps are in engineering and scientific reasoning: frontier models now match or exceed expert-level performance on many technical tasks, and increasingly act as collaborators that plan, code, simulate, and design (as we show in our own research on self-improving agentic discovery systems). Understand these technologies deeply is critically, both the foundations and how they're applied to critical industrial problems at scale, and to use them to drive innovation and technology development. This July 27–30, I will teach Applied AI for Materials Discovery at @MITProfessional (live online so you can participate from anywhere). It's a hands-on deep dive into the shift from predictive ML to agentic, closed-loop AI-native discovery and innovation. Highlights: ▶ AI scientists & recursive self-improving swarm intelligence: massively parallel agents that read literature, formulate hypotheses, write and run code, and critique each other's work ▶ Generative AI for inverse design: diffusion and flow matching for proteins, alloys, metamaterials, and crystals ▶ Foundation models that "think" physics: graph transformers, neural interatomic potentials, neural operators and PINNs ▶ Bridging the reality gap across scales: connecting atomic-scale agents to physics simulators and product-scale (DFT, MD, FEA) for automated verification of AI-generated designs ▶ Building custom reasoning models: fine-tuning, RL; incorporating first-principles physical agency (e.g. MCP, tool use) ▶ Unlocking dormant knowledge: turning unstructured data (papers, patents, lab notebooks, legacy PDFs, etc.) into structured, actionable insight ▶ Interpretability, reliability, and enterprise deployment The course will provide you with ready-to-use agent templates, dozens of code notebooks, repos, and curated datasets you can deploy immediately in your organization. More details on the course and registration link, see reply.

RT @tunguz: Our Anthropic overlords deciding which prompts the peasants are allowed to use.

I got a good nights sleep and I’m still just as angry about Anthropic’s choices. I enjoy working in AI so much and to have my access to the cutting edge models for my work rugpulled in an under the table fashion is appalling. I expected to be restricted eventually, but not now, and to be told it directly.
