That really depends on exactly what definition you are using. I suppose you could argue that yogurt could be made at home in a normal kitchen, but cheddar cheese couldn't. And I've never actually seen anyone make sauerkraut, though people certainly used to do so.

I.e., the first published definition of "ultraprocessed" specified "things that couldn't be made in a normal kitchen". I'll agree that it's a very sloppy definition, but I haven't heard a better one.

It varies from time to time. In the 1940's it was common for folk to get tattoos, at least in the US Navy. Ozzy the iceman was covered with tattoos. (Of course, since he was killed it might indicate that he was something analogous to a criminal, but probably not.)

The real problem is that minimally processed food doesn't keep as long, and often takes more time to prepare.

Actually "ultraprocessed" is too broad a category. It includes things like cheese and yogurt. Probably also sauerkraut. But there definitely are ultraprocessed foods that should not be sold without a strong warning, and many do have deceptive advertising that appears intentionally deceptive.

Excellent:

"In the US, the two major parties are indistinguishable in intent, that is, to keep their jobs."

Attacks by President Trump cause many people in government to avoid saying what they actually think. They don't want to lose their jobs.

Technology is moving ahead very fast!

Dude, learn about punctuation if you want to be understood.

That wasn't *all* I said, but it is apparently as far as you read. But let's stay there for now. You apparently disagree with this, whnich means that you think that LLMs are the only kind of AI that there is, and that language models can be trained to do things like design rocket engines.

That's what I just said.

Here's where the summary goes wrong:

Artificial Intelligence is in fact many kinds of technologies. People conflate LLMs with the whole thing because its the first kind of AI that an average person with no technical knowledge could use after a fashion.

But nobody is going to design a new rocket engine in ChatGPT. They're going to use some other kind of AI that work on problems on processes that the average person can't even conceive of -- like design optimization where there are potentially hundreds of parameters to tweak. Some of the underlying technology may have similarities -- like "neural nets" , which are just collections of mathematical matrices that encoded likelihoods underneath, not realistic models of biological neural systems. It shouldn't be surprising that a collection of matrices containing parameters describing weighted relations between features should have a wide variety of applications. That's just math; it's just sexier to call it "AI".

Damn. You're right. That article doesn't say it, and I didn't find the one I originally read, which was about bacteria living deep in the earth where the radiation generated ionization states that they used. IIRC it was about bacteria living in a granite based low-level uranium source. And they were living a lot deeper than previously detected bacteria. (This was about 3-4 decades ago, so it's not surprising that I can't find that article. I think it was in Science News, but possibly it was in New Scientist. In any case, what I read was a magazine article. And it was rather explicit...though of course not detailed.)

They tried to do Jesus, but passengers kept calling security about a hippy boarding the plane.

Here's one reference, though not the orginal one I read.

Note that this is not DIRECTLY eating radiation, but that's still its energy source, as that's where the H molecule comes from. So to simplify, saying it eats radiation is not wrong.
