At the start of university courses, I used to flip a few hundred pages into a textbook and it would be inscrutable to me.
I would be excited, maybe a bit awestruck, that in 12 weeks time it would all make sense to me — because I would have built up the knowledge piece by piece.
you can literally wake up one day and be like “actually, fuck everything about my past and the self-sabotaging identity i had” and decide to live an entirely new life and be someone who always fucking wins. it doesn’t take a feeling or breakthrough moment or epiphany. only a decision.
This famous video filmed at the Sasquatch Music Festival 2009 is often shown in corporations, team working classes, etc. and it actually shows an interesting aspect in psychology: the role of leading with a example (even if weird) and imitation.
The math on this project should mass-humble every AI lab on the planet.
1 cubic millimeter. One-millionth of a human brain. Harvard and Google spent 10 years mapping it. The imaging alone took 326 days. They sliced the tissue into 5,000 wafers each 30 nanometers thick, ran them through a $6 million electron microscope, then needed Google’s ML models to stitch the 3D reconstruction because no human team could process the output.
The result: 57,000 cells, 150 million synapses, 230 millimeters of blood vessels, compressed into 1.4 petabytes of raw data. For context, 1.4 petabytes is roughly 1.4 million gigabytes. From a speck smaller than a grain of rice.
Now scale that. The full human brain is one million times larger. Mapping the whole thing at this resolution would produce approximately 1.4 zettabytes of data. That’s roughly equal to all the data generated on Earth in a single year. The storage alone would cost an estimated $50 billion and require a 140-acre data center, which would make it the largest on the planet.
And they found things textbooks don’t contain. One neuron had over 5,000 connection points. Some axons had coiled themselves into tight whorls for completely unknown reasons. Pairs of cell clusters grew in mirror images of each other. Jeff Lichtman, the Harvard lead, said there’s “a chasm between what we already know and what we need to know.”
This is why the next step isn’t a human brain. It’s a mouse hippocampus, 10 cubic millimeters, over the next five years. Because even a mouse brain is 1,000x larger than what they just mapped, and the full mouse connectome is the proof of concept before anyone attempts the human one.
We’re building AI systems that loosely mimic neural networks while still unable to fully read the wiring diagram of a single cubic millimeter of the thing we’re trying to imitate. The original is 1.4 petabytes per millionth of its volume. Every AI model on Earth fits in a fraction of that.
The brain runs on 20 watts and fits in your skull. The data center required to merely describe one-millionth of it would span 140 acres.
je l’avais déjà anticipé au moment du rachat de Twitter par Elon mais la trajectoire que prend X est tout simplement incroyable
X suite la logique des systèmes complexes chinois comme Alibaba/Ant/ Tencent/WeChat/QQ où les frontières entre social, commerce, finance & infrastructure s’effacent pour créer une plateforme totale où tout se rejoint
in fine je pense qu’Elon va réussir à transformer X qui est à la base une plateforme sociale en une infrastructure cognitive distribuée qui capture, traite & monétise l’attention humaine à travers plusieurs couches (social, IA, robotique, énergie, transport & même spatial à + long terme)
pendant que les autres plateformes ajoutent des features, Musk construit un système complexe adaptatif qui vise à devenir indispensable à travers tous les domaines de la vie humaine oui c’est ambitieux au point de sembler délirant mais c’est exactement cette vision holistique qui différencie les plateformes qui survivent de celles qui dominent
et pour finir je pense aussi que vous verrez sans doute d’ici quelques années les premiers ponts entre les BCI et un réseau social comme X (les chinois feront la même chose) notamment à travers son autre boîte Neuralink et ça, ça sera sans doute la chose la plus excitante mais aussi la plus terrifiante que vous verrez de votre vie tant les applications cognitives vont être nombreuses et complètement folles
Musk contrôle X et l’IA qui le pilote (Grok/xAI) et prochainement l’interface cerveau-machine (Neuralink) avec tous les composants nécessaires pour créer la première plateforme social-cognitive directe
ça sera la fusion complète entre pensée humaine et infrastructure digitale où la frontière entre utiliser une plateforme et penser sur une plateforme disparaît totalement
ce virage n’est pas juste technologique, c’est anthropologique car il va redéfinir ce que signifie être humain à l’ère de l’interface cerveau-machine (sujet dont j’ai souvent parlé ici à travers les différentes innovations BCI et ma grande passion pour la complexité du cerveau biologique)
Musk connecte absolument toutes ses entreprises de Tesla à SpaceX en passant par X / xAI et Neuralink avec une profonde vision systémique et c’est à la fois fascinant et terrifiant à observer

Crypto is…
Desperate gamblers chasing their first bag.
Investors funding the buildout of the global casino.
Bankers hypnotizing the masses to collect their vig.
…all meaningless and ephemeral without the cypherpunks, who defend the dream of encrypted and unstoppable cash.

write your thesis on public key cryptography at the image sensor level
Proof of Physical capture will become a backbone of society soon.
