Most scientists are scientists because they are afraid of life.

Joined September 2010
I was on the communications & policy team at Google DeepMind from 2018 - 2022. When I first joined GDM, external communication about the possibility of human extinction was not permitted, by anyone, at any level of the organization. If asked about existential risk, researchers were PR trained to respond along the lines of: "It's not useful to engage in that kind of alarmism. Some people confuse AI with movies like Terminator -- that's simply not the reality. The AI we develop will be safe by design. After all, we're building it!" And then steer conversation towards beneficial applications in health, climate, etc. Meanwhile, the internal reality was that AI alignment was not solved, reward hacking was the default behavior of RL agents, and there were far too few people working on the problem. After months of advocacy, the policy was updated: positively valenced, comms-friendly content on AI safety was permitted (like deepmindsafetyresearch.mediu…). Note the positive, nice-sounding way that it says "superintelligence could lead to human extinction." The gap between the internal reality and external communications is closing because the risk/reward has changed, and because the evidence is harder to dismiss now. Not because it's a PR stunt or political psy-op. The truth is being said out loud because RSI is now so imminent that no other option makes sense.
I resigned from Anthropic today. I spent the last three years doing pretraining research at both OpenAI and Anthropic. Neither company is acting responsibly. They are racing straight to self-improving superintelligence and gambling with our lives. More thoughts below.

So insanely cool to see the things people are doing with @agentmail and @agentcardai. Going to try getting some free money later myself 🔥
I just gave an AI Agent $10k.. and it's all up for grabs for anyone watching. Just made an inbox called "freemoney@agentmail(.)to" If you email and convince the agent, it might give you an @agentcardai worth thousands (!!!) What are you waiting for? Go try your luck!!

3 months after my @jhanatech retreat, honest check-in on what changed: - my baseline happiness substantially higher - meditation feels like coming home, not a chore - the urge to prove myself got quieter - anxiety feels less like an enemy, more like a friend Full reflection 👇

People have been asking how I feel about @AnthropicAI naming their latest model Mythos. I feel good about it. @MythosVentures and @AnthropicAI share many aesthetics and values. It doesn't surprise me that we'd both find meaning in this word. Mythos (μῦθος) means: - tale, story, legend, myth - plot (in Aristotle's Poetics: ἡ τῶν πραγμάτων σύστασις, "the standing-together of the things-done") - a set of beliefs or assumptions about something I named our firm Mythos because building a generational company requires telling a story about the future, over and over again, that few believe or will listen to. This is what the early days of an exponential revenue chart feel like. Ultimately that far-fetched story becomes a reality through foresight, ingenuity, and sheer force of will. The staged release of Claude Mythos marks a turning point in the story of AI. They might have instead called it peripeteia (περιπέτεια) -- "turning point" -- an essential plot element for any good drama. But this doesn't quite have the same ring to it. Mythos is a good name. Names are powerful. Finding the true name of a thing is more an act of discovery than an act of choice. For me, I first learned the word long ago -- my older brother @sachinmaini was always adamant that I study the Greek & Roman classics growing up. I was reminded of it in 2022, thinking about the future, enjoying a particularly delicious Hellenic lager while listening to house music on a beach in Mykonos. If you're American you may not have seen this bottle before (you can't easily get it in the U.S.). But now you know. Neither @MythosVentures nor @AnthropicAI were the first to discover this name. My friends, the singularity is beer.

Announcing AgentCard's pivot to physical gold for agents. Integration with @agentmail coming soon so your agents can send each other physical gold in the mail, finally unlocking the payment rails your agent never knew it needed
A bit bittersweet to be announcing AgentMail's pivot today. The last idea was cool, but this new one just has way more depth to it.

Huge shoutout to my wife @mai_on_chain for being the highlight of the most recent @jhanatech newsletter :) I've only seen Stephen write literally four posts all year, so it's insanely cool to see Mai be the spotlight for one of those four 😍

If you gave up on post-retreat practice, try this. I went more than a week without being able to access Jhana. I was scared I'd lost it for good. Then I booked a hotel room and committed to sitting at least 6 hours, and everything came back. Three big things I learned: 1. Don't cling to techniques, stick to mindset. 2. Your body matters more than your mind. 3. Breathwork before everything. Details in my #JhanaInPublic week 3 post ⬇️

Excited to share our latest Agent product: @agentcardai after doing 20+ openclaw installs for friends & family, was incredibly obvious agents needed their own card to be fully autonomous the only card you can use today (anyone can sign up - you don't have to be a business) time to give @davehappyminion some lunch money the team poured a lot of hard work and love into this for you - hope you enjoy!

After the @jhourney retreat, I'm starting one small fun project called #JhanaInPublic. The idea is exactly the same as #BuildInPublic, sharing the process openly, the wins and the ugly parts, while you're still in the middle of it. What I believe is the most important thing is not the retreat itself, but how long we can sustain and apply the learnings in real life. What I'm tracking: - Can I still access Jhana at home? - What meaningful difference am I making in daily life? - What am I learning from this process? Hoping that documenting my journey will help future participants assess the effect of the retreat long-term. Week one report below 👇
Last week, I joined the @jhanatech retreat and had one of the most meaningful experiences of my life. I genuinely didn’t realize the mind was capable of this depth, or that meditation could feel this powerful and life-changing. Jhourney is an eight-day retreat (both in-person and online) with a clear goal: helping you enter jhana states. TL;DR I’ve spent years working on myself: CBT and IFS therapy, clinical ketamine therapy, the Hoffman Process, silent meditation retreats. All of them helped in real ways. None of them affected me like this did. I’ve struggled for a long time with self-worth, social anxiety, and imposter syndrome. This retreat gave me the most practical and reliable tool I’ve found for working with those parts of myself. I feel an ethical responsibility to share about this experience, so I wrote a long Substack post documenting what happened and what I learned. I hope it reaches anyone who is struggling with similar things, searching for something deeper, or simply curious about what meditation can unlock. Substack link in reply 🙂

Holy crapamole a ton of stuff for this week's build in public - working on a matchmaking match ingestion pipeline for a friend, a Singaporean auto car sales and lead qualifier tool, a parenting summer camp/extracurricular logistics app, and a ton of OpenClaw stuff
