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. 🧵

A lot of people are confused about whether a perfect upload of you running on silicon is conscious. Possibly:
1. Substrate chauvinism thing. Like carbon is magic
2. Province and continuity
3. Something as magical as consciousness not be made explicit (searle

This.
I don't get how otherwise smart, technical people can get so confused about this?

EA wants you to put you in a pod where you abandon your flesh to live in a simulated utopia that minimizes the damage you do to the world.
Accelerationists want you to become like gods, conquer the universe, and have lots of sex.

1M "people" on Mars looks more doable if the "people" can be ems.
SITUATION DETECTED: SpaceX has approved a new compensation package for Elon Musk ahead of its IPO.
200M super-voting shares if SpaceX hits a valuation of $7.5T and establishes a Mars colony of 1M people. He gets nothing if they miss targets.

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.
Community note
Waymo data (170M miles) shows a 92% reduction in serious injury/fatal crashes vs human drivers. While the post claims 2M jobs will be lost, BLS projections show transportation sector growth. Safety tech historically shifts labor roles rather than eliminating total employment

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

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

Thank you to the neuroscience community, we're standing on the shoulders of giants! Especially Janelia, @FlyWireNews, @srinituraga et. al, @neuromechfly <3
Also thanks to our advisors @robinhanson, @geochurch, Stephen Larson, @KordingLab, @anderssandberg, Ken Hayworth, and many more!

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?

The fly cannot fly quite yet because we don't know how to interpret the motor neuron outputs. only the brain was scanned. This is one of the reasons why we want to scan the brain and body. Then it won't require careful behavioral studies where you're watching motor neuron activity and seeing how the fly behaves, how it flaps its wings and such

In the case of this fruit fly the weights are determined by how many synapses are connecting to neurons, where the weight is linear with the number of synapses connecting. In the future we'll use a lot more sophisticated modeling based on neuron size and other cell morphology.
