We've uploaded a fruit fly. We took the @FlyWireNews connectome of the fruit fly brain, applied a simple neuron model (@Philip_Shiu Nature 2024) and used it to control a MuJoCo physics-simulated body, closing the loop from neural activation to action. A few things I want to say about what this means and where we're going at @eonsys. 🧵

@ohlennart In order of most relevant to least relevant: devs, pantheon, transcendence, the matrix. Lots more stories: luminous, crystal nights...

someone was trying to trick me into watching a movie. unfortunately my niche interests cannot be fulfilled. “Films where a data center is genuinely central to the plot (not a single scene, not "Al lives somewhere") is a vanishingly small category.”

Waymo is so good at saving lives that if it were a new drug in trial, it would hit the bar for being unblinded and made immediately available to the control group for ethical reasons. @MorePerfectUS would prefer to keep killing pedestrians.

NEW: If Waymo gets its way, 2 million workers will be out of work. When Waymo gets a firm hold on a city, wages go down. Some drivers now have to work 12 hours day, 7 days a week just to get by. This isn't inevitable — but Big Tech is spending millions to make you think it is.

Necome actually allowed me to visit their lab. I watched them preserve a rat brain, and collected samples from it myself. I brought the samples to a third party to image and analyze, and another third party neuroscientist to confirm: they're indeed preserving connectomic detail.

The flywire/janelia brain was preserved with aldehyde fixation. @aureliasong just published how she scaled the same approach to whole large mammal brains: every synapse (randomly sampled, and verified by BPF), connectomically traceable. Uploading is still years out. But preservation is step one, check out their article

Does anyone know how this virtual fly moves *without* RL, given that the actual motor neurons weren't traced out (because the body wasn't scanned)? @Leokoz8 @michaelandregg @oh_that_hat @eonsys @alexwg @Philip_Shiu @AdamMarblestone
Hattie Zhou@oh_that_hat

There's a fruit fly walking around right now that was never born. @eonsys just released a video where they took a real fly's connectome — the wiring diagram of its brain — and simulated it. Dropped it into a virtual body. It started walking. Grooming. Feeding. Doing what flies do. Nobody taught it to walk. No training data, no gradient descent toward fly-like behavior. This is the opposite of how AI works. They rebuilt the mind from the inside, neuron by neuron, and behavior just... emerged. It's the first time a biological organism has been recreated not by modeling what it does, but by modeling what it is. A human brain is 6 OOM more neurons. That's a scaling problem, something we've gotten very good at solving. So what happens when we have a working copy of the human mind?

@kanzure @alexwg We haven't explored this but to give a sense of how robust brains are, in Flywire brain only 40% of the synapses traceable to a cell body. So 60% of the synapses visible in the electron micrographs were not traceable to cell bodies. So we did not include them in the simulation.

@alexwg How many neurons or synapses can you delete before the behavior doesn't match?

@gpl_94 you made this possible. Grateful for your vision and support from the beginning! it takes a lot of conviction and independence to take a chance on something so far out of the overton window as uploading🚀🔮
george@gpl_94

Grateful to have been the first investor in @eonsys back in 2023. What @michaelandregg and team have achieved on a modest budget is incredible. Meanwhile hundreds of billions are flowing into AI compute while connectomics—the actual blueprint of intelligence—remains underfunded. The Overton window is shifting.

@michaelandregg @FlyWireNews @Philip_Shiu This is going to change everything if it scales up. If whole brain and body simulations work with mice, it'll probably work with humans. So the biggest step is really from flies to mice. Question, when do you plan to add body scans and behavior plasticity so it can learn?

@agapekeleta @FlyWireNews @Philip_Shiu Can't share too much right now but it really depends on funding. I think it's a massive microscope scanning challenge + image processing (stitching, tracing, segmentation, proofreading) but a known engineering problem. The biggest uncertainty is the neuron modeling part.

@michaelandregg @FlyWireNews @Philip_Shiu Awesome! What are your predictions for the timeline of modeling the full human brain connectome? How much money would need to be spent on this project, how feasible would it be, and when will it happen?

Brain emulation allows humans to flourish in a world with superintelligence. We're a small team in San Francisco working on what I believe is the most important technology of this century. Reach out if you want to help build this! 🚀 eon.systems
