Confused me for a second, because I just saw this about growing teeth, which is aiming for reaching market in 2030, which is relatively soon. So hopefully you'll be able to see that before people start shoveling dirt at you.

Yeah, or if it's at all targeted, or affects the entire mouth. If they can get a missing tooth or two to regrow, that would help a lot of people. If you start getting teeth sprouting up everywhere that need to be surgically removed, that would be a lot less universally applicable.

Same for whether it only works once, or if it develops new buds. Gotta say, it would be nice to make it to grave with a full set of teeth, since people losing their teeth has a huge impact on their quality of life.

While that's true, this isn't a specific engineering problem. You need to grab a single cell from each relevant subcluster of neurons in the spinal cord, spatially record the exact positioning, send it off to have RNA seq. done, sample all of the subclusters of the target area, spatially record exact positioning, send it off to have RNA seq done, resample based off of RNA seq data, begin axon regrowth of a single subcluster, and then repeat after every growth cycle to ensure the targeting is holding.

You can improve RNA sequencing machines to reduce runtime, improve spatial tracking to make it easier to keep track of the anatomy, but without sci-fi advances in implant technology you can't get around the sheer amount of procedural time requiring MD-PhDs and post docs to be involved in every visit.

One of the issues with medical technology is that we know far more about how the human body operates than we can control, so compared to biological structures our manipulation of biology at the cell specific level is relatively crude. I'm not saying tech won't catch up, but it's going to be ruinously involved for a very long time.

Well, you'll be pleased to know there are a lot of projects working on indoor vertical farming. Both as a method to spin up food production in heavily populated cities, and as a method for sustainable Mars and Moon bases. Which are effectively just bunkers, in space.

It's a little grim, but there's a standard SCI (spinal cord injury) guillotine that drops a weight with an angled wedge to cause a near perfectly replicable SCI. The mouse is sedated, but it's not exactly a good time for the mouse.

But yeah, the alternative is testing on humans, which, I really don't think we need a reminder on why that's super illegal.

The difference though is that this treatment would require hundreds of hours of ongoing work from medical professionals for each treatment. What they did was use single cell RNA sequencing to determine which subpopulations of cells are supposed to connect and where, before stimulating cell growth and guiding each RNA mapped subpopulation to where it's roughly supposed to go. That's one thing for anatomically complete sub-millimeter spinal cord injuries in mice, but a massive endeavor for human spinal cords.

If you've seen the bioengineered cancer treatments where researchers grow immune cells to target a single individual's tumor, the amount of specialized work that goes into that pales to what current technology would require for this sort of spinal regeneration, and that's for relatively simple small scale lesions. Multiple lesions or large scale cell death could result in attempting to selectively guide millions of microscopic axons in neat clusters for over a foot.

I wouldn't be surprised if insurance companies refused to pay for cell regrowth, and instead went for implants that are comparatively much simpler to install and modify in brain-computer interfaces that skip over the damage. This is a great advancement and does open the door for recovering from spinal cord damage, but this is one of those treatments that people are going to get because they need to fill FDA trials and won't charge, or because the patient is filthy rich.

I don't think I've taken emotional damage like this since I discovered what rejection felt like.

Yeah, I remember when everyone was starting to get decent camera phones and then news articles started popping up about high schoolers being picked up by the FBI for producing child porn by sending nudes, and their girlfriend/boyfriend for seeing them. There was a bit of panic, that was then promptly ignored because "it'd never happen to us".

Can't imagine how different someones life would be if they were tagged as a sex offender before even turning 18.

You got downvoted a lot, but they are literally the exact same red flags. The only difference is the percent of men and women surveyed that view each thing as a red flag, but those are pretty similar with men being more conservative the women according to the poll.

There are a few standouts, but after looking at the actual poll its pretty obvious that the one or two "opinion" questions are overwhelmed by political flags.

Right, but they would have been the last, because who gets mad at Canada, really?

Eggcelent. We eagerly await the completion of your grand project.

I could have sworn I saw an article talking about how there were noise artifacts that were fairly obvious, but now I can't turn anything up. The watermark should help things, but outside of that it looks like there's just a training dataset of pure generative AI images (GenImage) to train another AI to detect generated images. I guess we'll see what happens with that.

Yeah, I'd be uncomfortable, but immortality is immortality.

Now, if the requirement was a daily barebacking by the ultra-rich engineering their cum to be the elixir of immortality, I'd be a little more conflicted.

People say AI start hallucinating bizarre sentences is a problem, but I'm beginning to wonder if it simply gazed too deeply into the internet abyss.

Yeah, I always figured Canada would be the last to fall in nuclear holocaust because they're, you know, Canada. Yet here we are.

Feels a little like an Eldritch corporation that doesn't totally understand humanity, but produces simple guides to existence in a an effort to ease the suffering of our poor squalid souls.

Always nice to know someone appreciates me.

Thank you, PM_Your_Nudes_Please, for an wonderfully insightful comment on the nature of statistics in transportation accidents.

Imagine the timeline, Elon never became an asshole, the ultimate pyrotechnic show, fireworks going off, this strange happy man has flamethrowers and a jetpack, behind him a dozen synchronized Falcon 9 rockets take off and engage in a choreographed aerial ballet.

People post videos of it online, because Twitter still exists as a functional platform.

Yeah, right now the fight is between corporations and creators, but I feel like the future battle is going to be between corporate AIs and "pirated" ones, because Disney is going to keep a firm chokehold over what its generative AI can make, while the community ones will completely ignore copyright restrictions and just let people do whatever they want.

Not gonna need to worry about paywalls when you can get a pirated generative AI to create the superhero mashup you always wanted to watch as a child. That said, I could definitely see Disney and other piggybacking off of AI panic to extend copyright protection into spaces that were previously fair use.
