The Sloppification of Peptides

Ironically that reads to me like a typical claudeism
Training corpuses (corpii?) have always had lies, propaganda, derangement, you name it.
The Latin plural of corpus is corpora. It gets used a lot in linguistics articles, perhaps other fields as well.
However given that in English we don't care eg about Latin cases, I don't think we should care all that much about Latin plurals. So corpuses is fine by me.
"Corpi" gets used as a hypercorrection, but it's deprecated in favor of the two previous.
"Corpii", as suggested above, is right out.
I often use corpora, because it's what's common enough. And I sometimes use nonsense plurals like octopodes just to be silly.
The reason I replied is because the OP appeared to be interested in the most accepted or used plurals for this word.
In truth, I don't think that's quite how it works, but I wouldn't be surprised if teams who scrape data for training apply weights in favor of data that is known to be generated prior to the GPT-3 era.
Btw, learning from your own generated data isn't necessarily bad, if you have an external source of validation. See how AlphaGo learned from self play for a simple example.
Source: look at how good Chinese models are.
I'd say at least 99% of all new youtube videos are AI generated video, whether taking snippets from other videos and voiceovering them, or just making entire fake personalities up from scratch. That number will raise to 99.99% soon.
There is no veracity to these videos, and within a year I'd say no one will ever be able to detect AI or not. This is exasperated by the fact that normal, real productions are being AI edited, and metadata or other non-visible means to detect AI or not will be meaningless.
Bluntly put, most people currently get their 'news' from Tiktok and Youtube. When I discuss current events with random, not-tech people, they all "believe" that if it's video, and on youtube or tiktok? It's real.
I cannot express how much the average Joe thinks, in their mind, "Something published on the Internet" is high in trust. I'm verbose, I talk to a lot of people, and there is an inverse relationship to computing skill, and Internet trust.
And using a computer to "do things" is not "computing skill", any more than driving makes one a mechanic, or ensures you understand a car engine.
I guess my point is, I suspect that the continued degradation of reporting, and news, conjoined with alternate sources being 'news sites', will continue to the point that "reliable source" is non-existent.
For example, imagine if every single post from a phone, such as "I see troops in City X' are seen as almost certainly faked. Or even, "I don't see troops in City X'. And if you think of it, certain sectors of society preferred the curated, more controlled news of the past. There may be attempts to purposefully destroy the credibility and believability of every and all independents on any platform.
Create a personality, have it trusted for months or years, and then show that its data was false. Doing this is easy with the tools today, doing it by creating one million such personalities with the same goal, is just as easy.
The end of truth for all is here now.
There is no point of trust now on the Internet. The cut off isn't just for AI, and training.
The cut off is for humans believing anything.
The blog post rightly points out we should get good at spotting all this but this is not the scary part, the scary part is that the audience for these ecosystems is not even humans, it's the big AI players like Gemini and ChatGPT, and those are places that a lot of people are going to get information and advice on things.
I use Gemini quite a lot and lately I've already noticed it's very quick to give me a broad spectrum vibe on some issue or topic and not good at all at backing it up with reputable sources. So I think this is potentially a very ominous development of the entire web itself becomes a giant poisoned cauldron of untrustworthy AI maliciously influencing "trustworthy" AIs.
Update: i fed this comment into Gemini and asked "what is Google doing about this?" and it produced a very long, detailed answer, leading off with tagging this as the so-called "internet ouroboros" problem. For those who don't feel like doing the same, I can distill it's answer as follows: "Yo. Chill. We got this, bro. Lol" so we're good!
No, they don't, it's a very Silicon Valley specific thing and I never heard about them here in France. People need to stop thinking their experience generalizes by default
Also, I'd add that gym bros definitely have heard of them, especially if they are familiar with steroids.
The GLP-1 drugs are probably the main cause of this. We have this amazing class of compounds that work really well, But are priced pretty high, at least considering lower UK wages.
So there is a big incentive to look at getting these much cheaper from China. You hear about this happening, and then you see the fact that these companies have big catalogues full of other peptides that are a crypto payment and a click away.
Not every aspect of american culture makes it overseas and much less does now than used to 20-30 years ago.
I think peptides (and medicating yourself out of a hole in general) are a pretty uniquely american thing.
We're amused by your antics but no one wants to emulate American culture anymore.
if I asked 20 of my friends about peptides I'm probably the only one that subscribes to that american leaning, peptide-spammed subreddit.
Maybe a US thing
it's not a sv-only thing.
I shall consult the zoomers.

They learn about it through Insta or Snapchat and take whatever is promoted by whatever big muscular guy.
It is legal to sell research only peptides that are not FDA approved, but as soon you talk about efficacy and human use, you also become a target for the FDA warning letters. [1] [2] [3].
Anyone selling these peptides who are indexed by search engines face increase scrutiny immediately, especially if you're going to try to sell the patented ones, because then you're a Target of not just the FDA but also Eli Lilly... peptides are big business but it's big risk if you do it wrong.... Eli Lily wants people spending $1,000 per month to use these peptides.
I think the trick about selling peptides to people is to probably do it word of mouth, no indexing by google, no ads, double gated website with invite only structure.

What disease does snake oil cure exactly according to you?
It is these American counterparts that dissembled the truth by creating ineffective variations of the formulas hence the twisting of the term, "Snake Oil Salesmen."

I think, if you wanted to find out about the topic you mention, you might first want to look for literature that would support such claims (even preprints on arxiv would at least be a start) before looking for actual products.
From what I've read there is some real risks associated with using them. Sounds a bit like the marketing of steroids in the 70s.
The drugs (coincidentally of shape "peptide") that have been through clinical trials are obviously measured against placebo, and they (like the approved GLP-related set of drugs) are outrageously effective beyond placebo. And have very little downsides compared to the downsides of being obese, which are far more immense than people appreciate.
The real question is: Should you be putting novel, poorly researched and dubiously manufactured substances (which happen to be peptides) in your body via injection? To that I say, to each their own but I'll wait for the pharma industry to catch up. I'm not that bored.
People don't seem to be regularly dying from peptides, at least not now.
on one hand: no, absolutely not, hell no.
on the other hand: these people are voluntarily doing human sperimentation. things like this are going to happen anyway so we might as well collect the data (samples, effect etc). it's not much different from the safe needles initiatives.
Narrowing down areas into "Anecdotally many people say it works, we should check" does have some value, even if it does just wind up debunking the claims
Life out of balance, indeed.
(Yes, eating healthy and exercising would probably help most people, but many remain)
Injecting poorly-studied grey market peptides seems like a bad idea.
Anyone talking about "taking peptides" as a meaningful sentence is absolutely dismissible in the same way someone talking about "taking chemicals" is dismissible.
1) PT-141 is a peptide that releases sex hormone into the blood and literally makes you horny, and its primary use is for premenopausal women that have low sex drive.
2) PNC-27 is a peptide that supposedly attaches to the cell membrane of tumor cells and performs cell lysis (death) of the tumor cell, and it's supposedly affects many different kinds of tumor cells: breast, pancreatic, lung, colon, ovarian, cervical, and leukemia
3) Epithalon is a peptide that is noted for extending telomers on chromosomes, leading to longevity benefits.
4) MOTS-c is it peptide that in animal studies is shown to boost physical endurance and mimic molecular changes associated with training/exercise.
Telomeres are part of your anti-cancer mechanisms (they stop cell reproduction after say 60 DNA self-copies to help fight unbounded cancerous growth).
If chasing 'benefits', you'd want to be careful before fucking with that mechanism.
50 years ago it was cocaine, 40 years ago there was crack, 30 years ago it was heroin, 20 years ago we had bath salts, 10 years ago it was gas station drugs and meth, 5 years ago it was Ivermectin, this year it's SF techies doing their own research into peptides and taking some. Taking the latest drug (or peptide in 2026) is its own benefit.
As with any substance, there can be use, and abuse. If you would have told people 30 years ago you use creatine, you would be stared at as if you inject steroids or growth hormone. Today it is in the supermarket, literally next to the protein bars. Throwing Ivermectin on the same pile as crack and heroin though.. :D
I am sure there are dozens (dozens!) of idiots who inject whatever they think it is for whatever reason, valid or not. Peptides is a craze, and it is also emerging here in the Netherlands, but as people have pointed out, lots of things are peptides, and lots of them seem to have significant health benefits, when used properly. Give it another 30 years... they will be next to the protein bars as well, once someone has figured out how to capture the profits.
If you artificially inject the correct protein into your body to mimic a naturally producing one, it would do the job and in that way peptides works. However, most of peptides injected by people are hardly human tested for long term effects. Human body is remarkable at adjusting and maintaining a baseline and we don’t know what would be the unintended side effects of these peptides because the body would try to counterbalance it. At best it could be just a mild headache or stomachache and at worst it could be cancer
Unfortunately many peptides break down in the GI tract. However there is some reason to believe eating protein, like collagen in meat does produce an outcome in terms of muscle mass and skin condition. I guess because those breakdown products make their way through the blood/lymph system to where they're needed.
All those people huffing Whey powder after Gym? peptides! Just enjoy a low sugar yoghourt at lunchtime guys. same-same
>"The trained eye, weary of vibe coded designs, will see Claude Code’s aesthetic fingerprint all over this. "
yeah, everyone is re-doing old interfaces with LLMs.
>"They're hosted on AlexHost"
yeah, they're selling grey market pharma.
Now, I have no problems saying that the whole thing is a bot driven scam -- it probably is , grey market web is filled with scams -- but there was no evidence given; just an ad for a magic tool that detects AI... somehow.
...which makes me feel like an asshole for putting in the time looking for the anchor and hoping it wasn't an advertisement.
