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.

🚨: Scientists mapped 1 mm³ of a human brain ─ less than a grain of rice ─ and a microscopic cosmos appeared.

Since April, my approach to #LanguageLearning has evolved in unexpected ways.
My daily use of @language_drops has dropped drastically, while my use of #LLMs has grown significantly.
I've developed a customized, cellphone-based #methodology.
More on this in the next posts 😉.

@jofrellombart @GerardInsa @moa_pio Jo cap a l'any 2001 em vaig canviar el nom al DNI. Als meus pares els havien obligat a posar-lo en castellà, el vaig canviar al català.

@moa_pio Mi padre tuvo que ser inscrito como Carlos. Carles estaba prohibido. Pero "sin apenas presión". Ni llamarse por su nombre podía.

@mellosemcor It shouldn't feel like this. It all depends on the level of command you want to attain in the new language.

@Claudiacatalana Val a dir que el català està en perill sobretot (però no únicament) perquè ens l'estem carregant nosaltres mateixos, cada vegada que -a la primera de canvi- ens passem al castellà, com bé saben a @mantincelcatala.
Una llengua que no es parla, és una llengua inexistent.

@soler_toni El trist no és que el #català estigui pràcticament acabat.
El trist és que ENS L'ESTEM CARREGANT NOSALTRES MATEIXOS.
I el que és encara més trist és que, segons la meva experiència, molts immigrants EN REALITAT AGRAEIXEN QUE SE'LS PARLI EN CATALÀ.
EL VOLEN APRENDRE❕

Amb un 13% els estem encabronant. Només que passéssim al 25% (per no dir un 50%) faríem un bon merder.
