Bryan Johnson explains why he started growing his own food instead of buying it from stores “We’ve learned that toxins are in almost every food. One example: I was eating lentils and the test came back high, so we started looking into why these lentils had high levels of heavy metals. We reached out to the company and found out they were using human sludge as fertilizer, and that’s how the heavy metals got into it” “I want to source my own food, test it, and know exactly what I’m putting into my body”

Alright, friends – my NEW Apple Vision Pro app Metaballs: Spatial has launched! 🤯 This was SO much work, and would mean the world to me if you share, and go download it today!

Agency > Intelligence I had this intuitively wrong for decades, I think due to a pervasive cultural veneration of intelligence, various entertainment/media, obsession with IQ etc. Agency is significantly more powerful and significantly more scarce. Are you hiring for agency? Are we educating for agency? Are you acting as if you had 10X agency? Grok explanation is ~close: “Agency, as a personality trait, refers to an individual's capacity to take initiative, make decisions, and exert control over their actions and environment. It’s about being proactive rather than reactive—someone with high agency doesn’t just let life happen to them; they shape it. Think of it as a blend of self-efficacy, determination, and a sense of ownership over one’s path. People with strong agency tend to set goals and pursue them with confidence, even in the face of obstacles. They’re the type to say, “I’ll figure it out,” and then actually do it. On the flip side, someone low in agency might feel more like a passenger in their own life, waiting for external forces—like luck, other people, or circumstances—to dictate what happens next. It’s not quite the same as assertiveness or ambition, though it can overlap. Agency is quieter, more internal—it’s the belief that you *can* act, paired with the will to follow through. Psychologists often tie it to concepts like locus of control: high-agency folks lean toward an internal locus, feeling they steer their fate, while low-agency folks might lean external, seeing life as something that happens *to* them.”

I call projects like this “Nat Friedman-punk” or “Friedpunk” for short. Cute, friendly, intelligible, and clearly beneficial for society. If the Terminator apocalypse comes, somehow this little guy is going to be fighting alongside you to the end.

We're using smart glasses to learn Chinese. Our friend Yazen used it for 4 months in Russia - he's now conversationally fluent. Smart glasses are the next shift in intelligence augmentation.
