There is stuff missing, of course (alt text for screencap contains about 3 toots' worth of text explaining this): information about how the motor neurons connect to physical features of the body like the muscles, information on morphologically divergent neurons and fine detail on dendritic branching and synaptic inputs across dendritic compartments:

Also shows that much "AI" terminology is marketing, not science. Computer "AI" doesn't have Neural Networks (it's a distributed dataflow database) nor "learning".I've suspected this result for decades.
"Uploading" human consciousness is still SF based on Transhumanism, which is a religion, not science.
I doubt it will yield anything for computer AI. Except current LLM based AI is a dead end.
-
@cstross Agreed that artificial consciousness might be possible from the bottom up, starting with agency and a complete model.
I don't believe for a picosecond that current LLMs (or other AI) are conscious.
I absolutely agree.
At best, what current LLMs are is evidence that linguistic processing follows statistically modelable rules.

But I'm REALLY HAPPY right now because this kinda-sorta validates the key premise of the SF novel I just handed in last month (which involves serial reincarnation via destructive brain-slicing-and-imaging then imprinting onto an immature cortex, and then explores its disastrous societal failure modes).
... And it also hints that artificial consciousness might, eventually, be possible, if only via the hard path of doing it the same way we do it, only in simulation in silico.

@cstross Does that make your work Science Fact-ion instead of Science Fiction?

Sigh.
So it turns out we've mapped the neural connectome of Drosophila *and simulated it in silico*.

@cstross "the wiring is the computer" is not too surprising. Years ago playing w/ algorithms for FPGA, needed to invent a bit-string perfect hash table. One way of doing a perfect hash function/table involves a matrix and offset, H = Mx + v, but our math needed to be boolean (AND, XOR), a "1" coefficient was a wire, and if we wanted a one-cycle hash index, then we needed no more 1's in a row than maximum inputs to an FPGA XOR. So, a sparse boolean matrix. The wiring was the computation..

Also since cryogenic freezing a brain destroys the structure of an already dead brain (basically deteriotated), the folk paying for that are being scammed.I agree it's nice info for SF world building.
Presumably they'd have to replace the blood of a living mouse with a special fluid to preserve the structure?

@cstross Wait- so... I should get my brain frozen until they perfect the slicing and uploading to silicon to live eternally

@raymaccarthy Yes on the blood-replacement, which implies—awkwardly, for the human uploading fans—that doing this to a human would lay the experimenters open to murder charges.

@CGM Already noted!

@Antiqueight Naah, the ice crystals forming in your synapses would mush them into un-digitizable soup.

... The next step on from Drosophila, the mouse brain, is 560 times larger—never mind a vastly more complex human brain. And to get the murine connectome we'll have to chop up *a lot* of brains: a human upload won't pass any kind of medical ethics review at this point!
But near-term, it's expected to yield "fundamentally new architectural principles for AI systems that are more sample-efficient, more robust, and more capable of behavioral generalization than current approaches"

@cstross > fundamentally new architectural principles for AI systems that are more sample-efficient, more robust, and more capable of behavioral generalization than current approaches
I expect Sam Altman to state that this is fake news and nobody can do things better than they do.
I also hope it'll cause panic-selling shares in all "AI" companies - but that is unlikely, it would require the average investor to have a larger brain than a Drosophila. -

Certainly a more promising avenue towards AGI than stochastic parrots.But then again, what they're doing here is copying a fly brain into a silicon black box and seeing what it does. The research has nothing to do with improving upon fly intelligence and immanentising the Fly Nerd Rapture.

I heard when they first got the fly simulation up and running it introduced itself as Elon Musk and said that it was going to set up a colony on Mars.
