There are a few dozen neurons in the bellies of crabs. They control the grinding motions of the stomach.

I would like to see a machine replacement for these neurons that functions just as well as the natural ones before anyone hooks anyone else up to an uploading anything.

Just ... someone please show we can understand how neurons even do things.

It's like building an autonomous drone before you know how to make a paper airplane. (in fact it's much worse than that)

@futurebird I have more or less the same feelings about the “colonize mars” crowd. Build a closed self-sustaining colony in like, Alberta first. Then we can talk.
@steve @futurebird To be fair, Mars doesn’t have Danielle Smith so it might be easier there than in Alberta. Or at least, less stupid.
@steve @futurebird ✋🏻is old enough to remember how much trouble the Biosphere 2 folks had
@karawynn @steve @futurebird Well, hopefully a colony on Mars would not be run but Steve Bannon, but with the way things are going with Elon, we can't eliminate that as a possibility. https://www.thedailybeast.com/spaceship-earth-tells-the-wild-story-of-biosphere-2-steve-bannons-eco-cult-disaster
‘Spaceship Earth’ Tells the Wild Story of Biosphere 2, Steve Bannon’s Eco-Cult Disaster

The new documentary “Spaceship Earth” examines the Biosphere 2 project—an ecological experiment run by none other than Steve Bannon (yes, the fascist ex-Trump adviser).

The Daily Beast
@steve @futurebird I have a similar opinion, but I'll make an exception to all billionaires who want to move to Mars right now.
@grumble209 @futurebird I like where your head's at; they're welcome to lock themselves into a colony in Alberta, too.
@grumble209 @steve @futurebird they are the world's most brilliant minds so it makes sense sending them first. If they can't make it how could we expect some random middle-class person to make it?
@futurebird C. elegans is right there! What's stopping the technoutopians? Why haven't they 3d printed a big plastic C. elegans to wiggle into the future?
@Wharrrrrrgarbl @futurebird one thousand cells total, _surely_ we can simulate the whole thing 😂
@Wharrrrrrgarbl @futurebird https://openworm.org/ - worth a visit if only for the large "Explore the Worm" call-to-action button
OpenWorm

OpenWorm is an open source project dedicated to creating a virtual C. elegans nematode in a computer.

@futurebird But that isn't exciting enough to get the attention of the press or, more importantly, investors.

And mind uploading is bunk and will always be bunk. I suspect it's a carrot on a stick to be dangled in front of investors forever, since it'll never actually be reached but the promise of immortailty is too good for some people to pass up so they'll keep dumping money into it indefinitely.

@linebyline @futurebird "will always be" seems like a stretch with no justification.

Are we centuries too early at best and all utterly fucked though? Almost certainly yes.

@lispi314 @futurebird A thing copied does not become its copy and no amount of technological innovation can change that.

@linebyline @futurebird That's largely irrelevant though.

Without some sort of metaphysical shenanigans being involved, a functionally perfect copy is basically indistinguishable from the original.

And those ways by which it may remain distinguishable hardly matter if they do not affect functionality.

@linebyline @futurebird

i think it's more like, for decades we have been shown, told, and sold a narrative about "the future", and our world has been built around this narrative of making fictional ideas real instead of solving already existing, real problems.

the capitalists aren't asking how they can reduce atmospheric pollution by not creating it, but instead how they can make profit by continuing business as usual but putting some duct tape and chicken wire around the problem so they can pretend it's fixed. first it was "carbon offset credits", now it's "how can we invent wacky new things and make profit from selling them to polluting corporations?", because part of the way the rich stay rich is by paying each other to be rich.

@futurebird this. The largest neural network models have roughly the same number of "neurons" as an insect, but instead of building them to do simple insect-like things, we're pressing them to replace jobs requiring human judgement and reasoning.

(yes, I'm aware that the analogy of artificial neural networks to biological ones is crude)
