The Thought Emporium documents building a multi-electrode array to grow human neurons and interface them with a computer.

Neurons are amazing little microbes capable of learning and making decisions. Modern AI tries to take inspiration from living neurons, but why settle for the synthetic version? By growing human neurons directly connected to a computer it's possible to make a living AI of sorts capable of even complex tasks like flying a plane in a simulation. Today we explore our first attempt at doing exactly that. We cover building the first prototype multi electrode array, growing the neurons and attempting to take some readings from them. This is the first part of what will hopefully be a many part series, so stay tuned for updates!

What people say. Recommended as an amazing and surreal demonstration of DIY biocomputing and interfacing living cells with hardware.

Seeing a dude grow human neurons directly connected to a computer chip to make a "human AI", all from his garage 0. It showed me what is possible with science these days if you have enough dedication and know-how. Made me feel deeply excited and scared for the incoming future. 0 link to this video

If you're interested in exploring direct neuron + computer integration, Justin Atkin from The Thought Emporium is attempting to grow neurons on an electrode array. Here are two episodes that cover his work: Growing Human Neurons Connected to a Computer - link to this video Connecting Neurons to a Computer: The New Plan - link

Interesting is understatement, it's a channel which is one of the closer ones to hard science on the hard science - pop science spectrum and still having more than a million subscribers. Some outstanding videos IMHO: The channel owner applies himself a gene therapy to fix his lactose intolerance. link How exactly the Covid Tests work: link Growing Human Neurons Connected to a Computer link to this video Especially the Covid test video was eye opening against the conspiracy theorist propaganda during the pandemic because knowing how tests actually work on practical level makes you see through the claims effort free.

On “Why Computers Won't Make Themselves Smarter”

Just yesterday 0 I also did an upper bound estimate on computing power of a human brain based on assumption that brains carry out irreversible computations. E.g. inputs of an AND gate can not be recovered from the gate output. This forces increase of entropy. This is known as Landauer's principle or Landauer's limit 1. The Landauer's limit suggests that a brain consuming 20W at 36C can carry out no more than ~1e22 irreversible operations per second (20W / (309.2K * Boltzmann constant * ln(2))). That bounds brains at ~1e21 FLOP/s (~10 bits erased per FLOP). The best supercomputer right now does ~4e17 FLOP/s. That's log2(1e21 / 4e17) ~11 doublings of computing power until supercomputers wi…
