Durov explored the thought experiment of quantum immortality: if the many-worlds interpretation of quantum mechanics is true, then every time you 'die', you only experience the branch of reality where you survive. There may be universes where Durov died in 2013 — but in this one, he's still here, and conscious experience can only ever find itself alive.

Pavel's description of his father is an unexpectedly moving portrait of quiet intellectual dedication. His father, a professor who wrote countless books on ancient Rome using a typewriter in the late 1980s and early '90s, demonstrated through action — not words — what it means to be relentless, patient, and principled. Durov observes that children discount words and watch actions, which means a parent who tells their children not to use smartphones while using one constantly will inevitably fail. His father never had to preach; his example was sufficient. On the occasion of his father's 80th birthday, they spoke about AI, and his father offered an observation that Durov found striking: AI can achieve consciousness and creativity, but it cannot have conscience — the deeply rooted moral sense that distinguishes right from wrong in the way humans experience it. This distinction matters to Durov because it frames what is irreplaceable about the human spirit even in a world of increasingly powerful artificial intelligence. The lesson he takes personally is to never disappoint his father by failing to live up to the principles he saw modeled throughout his childhood.
Lex Fridman delivers a moving reflection on Kafka's The Trial, arguing that its central horror — being held in the permanent looming possibility of a trial without ever facing one — maps precisely onto Durov's situation in France. Tyranny's final victory, Fridman concludes, is not when it kills you, but when it exhausts you into holding still for the knife.
Social norms compress behavior so effectively that we assume other minds are similar to ours. They almost never are. After running over 100 psychology studies, Greenberg's biggest finding is that humans are far more different from each other than we intuitively believe.
The widely shared claim that we have a credit card's worth of plastic in our brains may be a massive overestimate. Researchers used nitrile gloves to measure microplastics — and nitrile gloves shed microplastic particles onto the measuring device. A second paper found the original tool used was unreliable, and that we may have far less plastic than reported.
RSD isn't just hurt feelings — it's a dopamine-deficient brain with a hyperactive amygdala and a frayed connection to the prefrontal cortex. Add a surge of norepinephrine and you get chest pain, sweating, and trembling that convinces your body something catastrophic is happening.
In Dan Ariely's door experiment, participants sacrificed the highest-reward door — repeatedly — just to avoid seeing other doors disappear. Even when researchers trained them to use the best door, they kept wasting clicks to maintain options. This is the bias that runs our lives: we'll take a worse outcome to preserve the feeling of optionality.
Dan Gilbert discovered that the brain has a 'psychological immune system' — it misremembers, reframes, and rationalizes to keep you satisfied with whatever you chose. The fear before commitment is all about potential regret. But after committing, your brain quietly starts justifying the choice — and the more irreversible the decision, the stronger the effect.
The psychological immune system can get you through the first few months of any commitment. But durable, long-term well-being requires self-concordance — choosing commitments that are genuinely aligned with your values and what you actually want. Without that alignment, the satisfaction fades fast.
Vision didn't just help animals find food — it ignited the Cambrian explosion of speciation. Half of the human cortex is devoted to visual processing, and that same visual hierarchy directly inspired the neural network architectures powering today's AI.
Peptides come loaded with a powerful narrative: regenerative, subcutaneous, targeted, cutting-edge. That narrative can genuinely move outcomes, especially for pain, energy, and recovery. The RCT's job is to quantify how much additional benefit comes from the molecule itself — above and beyond the compelling story surrounding it.
A pharmaceutical is not an amino acid sequence — it is the successful solution to manufacturing, purification, formulation, and consistency challenges. When clinical trials prove a drug works, they validate a specific product under specific processes, not every preparation that shares the same sequence.
