Neuralink and the Brain's Magical Future — Wait But Why
The neuroplasticity that makes our brains so useful to us also makes them incredibly difficult to understand—because the way each of our brains works is based on how that brain has shaped itself, based on its particular environment and life experience

We look at the world, and there’s just this physical 3D world out there—like you look at a cup, and you just see a cup—but what your eyes are seeing is really just a bunch of pixels. And when you look in the visual cortex, you see that there are roughly 20-40 different maps. V1 is the first area, where it’s tracking little edges and colors and things like that. And there’s other areas looking at more complicated objects, and there’s all these different visual representations on the surface of your brain, that you can see. And somehow all of that information is being bound together in this info…

there are multiple levels of features

In neural networks, the features are automatically learned from raw data.

One interesting question is whether information stored in digital form will last as long as analog information
Analog and digital technology - What's the difference?
You'll need several shelves to store 400 vinyl, analog LP records, but with an MP3 player you can put the same amount of music in your pocket!
Analog and digital technology - What's the difference?
easier to store information in digital form and it generally takes up less room.
Analog and digital technology - What's the difference?
Cellphones, for example, transmit and receive calls by converting the sounds of a person's voice into numbers and then sending the numbers from one place to another in the form of radio waves
Analog and digital technology - What's the difference?
measuring devices that are now likely to give you an instant digital reading.
Analog and digital technology - What's the difference?
we first convert the information into numbers (digits) and display or store the numbers instead
Analog and digital technology - What's the difference?
recording sounds with an old-fashioned cassette recorder. The recording you make is a collection of magnetized areas on a long reel of plastic tape. Together, they represent an analogy of the sounds you originally heard.
Analog and digital technology - What's the difference?
An old-style film camera is sometimes referred to as example of analog technology. You capture an image on a piece of transparent plastic "film" coated with silver-based chemicals, which react to light
Analog and digital technology - What's the difference?
The human collective knowledge tower now lived in physical form, neatly organized on the shelves of city libraries and universities.

with a vastly larger body of knowledge shared among a vastly larger group of people, memories alone would have had a hard time supporting it all, and most of it would have ended up lost.

More conversations meant more ideas bumping up against each other, which led to many more discoveries clicking together, and the pace of innovation soared.

tribes over time to begin to settle into permanent locations and merge into organized super-tribes. When this happened, each tribe’s tower of accumulated knowledge could be shared with the larger super-tribe, forming a super-tower. Mass cooperation raised the quality of life for everyone

Language gives a group of humans a collective intelligence far greater than individual human intelligence

a nervous system boss. The boss lived in the flatworm’s head and had a rule that all nerves in the body had to report any new information directly to him

the world’s first nervous system—a nerve net.

The human brain had advanced to the point where it could understand that even though the sound “rock” was not itself a rock, it could be used as a symbol of a rock—it was a sound that referred to a rock. The early human had invented language

Over the next few million years, the new boss grew older and wiser, and his ideas kept getting better.

the early version of the neocortex, and though he didn’t say much at first, as evolution gave rise to primates and then great apes and then early hominids, this new boss grew from a baby into a child and eventually into a teenager with his own idea of how things should be run.

The flatworm’s boss-highway system was the world’s first central nervous system, and the boss in the flatworm’s head was the world’s first brain.

So, for any process that goes between the same two thermodynamic equilibrium states, the maximum non-expansion work that the system can do on its surroundings is
