AI “loses its mind” when fed AI-created drivel

In other words, without “fresh real data” — translation: original human work, as opposed to stuff spit out by AI — to feed the beast, we can expect its outputs to suffer drastically. When trained repeatedly on synthetic content, say the researchers, outlying, less-represented information at the outskirts of a model’s training data will start to disappear. The model will then start pulling from increasingly converging and less-varied data, and as a result, it’ll soon start to crumble into itself.

So, as more and more lazy people ask AI to “write” for them, the programs get less and less accurate…

Or, as the authors of the study conclude, “…without enough fresh real data in each generation of an autophagous loop, future generative models are doomed to have their quality (precision) or diversity (recall) progressively decrease.”

I.e., the use of AI-generated content to train AI doesn’t work, and since there is already way too much AI-generated garbage all over the internet, it’s almost impossible to sort out which is which when the AI-creators “scrape” data from the web.

So…

See, machines can’t replace us entirely — their brains will melt!

But then again, that might not be so hopeful after all. When AI takes over the world, maybe it won’t kill humans; perhaps it’ll just corral us into content farms… 

At least we won’t wind up as batteries.

Yet.

PS. I find it both hysterically amusing and disturbing that my blog program offers an “experimental AI assistant.” Granted, the program does let you know that AI-generated content accuracy is not guaranteed, but wth would I want to use AI for a personal blog? The whole purpose of a blog is to WRITE. AI-generated text is not writing. It is intellectual property theft.

Synthetic human embryos – yeah, now *that’s* not controversial…

The synthetic embryos – only days or weeks old – could help researchers study the earliest stages of human development and explain pregnancy loss. 

Nobody is currently suggesting growing them into a baby.

Well, that’s a relief….

This is the first time that has been achieved using human material. Although, they are not truly “synthetic”, as the starting material was cells cultured from a traditional embryo in the laboratory.

Great, but…

She has already developed synthetic mouse embryos with evidence of a developing brain and beating heart.

Come on, BBC. I think you can see where this is going…

Meanwhile, scientists in China have implanted synthetic monkey embryos into female monkeys – although, all the pregnancies failed.

Yep. Straight to the monkey house.

Seriously, did scientists actually think this was not going to cause a whole lot of people to get upset all over again?

Natural embryo (top), synthetic embryo (bottom). They look pretty similar…

This may indeed be a good way to study infertility causes and how embryos develop, but even the possibility of creating an embryo from a stem cell should have set off warning bells. 14-day limit or not, somebody’s going to get really tempted to do something else with them…

I’m thinking up all sorts of SciFi stories from this…

fMRI, GPT-1, and your brain

Scientists have found a way to decode a stream of words in the brain using MRI scans and artificial intelligence.

While not perfect, this is some seriously scary stuff.

FWIW the researchers themselves did recognize this…

Although it’s nowhere near being able to decode spontaneous thoughts in the real world, the advance raises concerns that, with improvement, the technology might mimic some type of mind reading. “Our thought when we actually had this working was, ‘Oh my God, this is kind of terrifying,’” Huth recalls.

Participants have to consent to being “read,” and there are ways to prevent the software from figuring out even the “gist” of what they were thinking.

Still, imagine if some nefarious criminal group (or governmental agency, if there is a difference) decided to force someone to consent to have their thoughts read.

Long distance.

Permanently.

It’s getting harder and harder to distinguish scifi from reality.

Researchers can now “see” you using WiFi

Interestingly, they position this advancement as progress in privacy rights; “In addition, they protect individuals’ privacy and the required equipment can be bought at a reasonable price,” they wrote.

If you’re not scared of tech yet, you should be.
