Most organic molecules feature a lot of hydrogen that essentially serves as a placeholder for all the free bonds of carbon (and there is plenty!), oxygen, and nitrogen. Hydrogen is essentially the default thing to connect to about any organic molecule. And yes, it is primarily taken from water in the grand scheme of things.
To expand on that, hydrogen is just lone protons. Some of those protons pick up an electron, but if it’s a proton, it’s hydrogen. And considering that nuclear fusion is hard^[citation needed]^, it makes sense that one of the most common things to attach to other atoms would just be the smallest, most abundant, and most simple kind of atom out there.
Hydrogen is an electron and proton. I am guessing that most protons have been fully ionized many times since the beginning of the universe, thus not being complete intact atoms. Checkmate scientists!
As far as I’m aware, protons don’t decay. If they formed at the beginning of the universe, they stick around until they get annihilated by anti-matter. But are we getting new protons after the universe formed? No idea.
I’m a biologist rather than a physicist, but I will take a swing at this.
Not really, although it depends on how you do your definitions. Most of the elements were formed by stars, which were themselves formed by the OG hydrogen, so hydrogen came first. So, first energy, then particles, then hydrogen, then stars and such, then oxygen and iron and all of those things.
It’s Hydrogen that’s existed since the universe cooled enough for electrons and protons to make atoms. Seconds after the big bang.
That’s most hydrogen.
It’s never been fused into heavier elements just still sticking around and caught in the planetary part of the solar system rather than the sun itself. Or any previous suns.
There’s some helium like that but most helium was formed inside suns later, and heavier elements all formed later in suns or supernovas.

Don’t forget neutron star collisions. Modern physics doesn’t think there’s enough energy in supernovae to create all the elements, so some must have come from neutron star collisions.
More like 380,000 years after the big bang you still needed everything to cool down and forces to separate and lots of other really cool stuff to happen before hydrogen could form.

Atoms didn’t exist until 380,000 years after the big bang. Before that the universe was too dense for atoms to form and everything existed as a hot dense plasma where no electron could be captured by protons and neutrons. The protons that make up the nucleus of hydrogen did exist, it’s just that everything was too energetic to become an atom yet.
I get the sentiment but wouldn’t you WANT an AI to be trained on your own words? That would make the AI more favorable to your points of view. By self-censoring you effectively let everyone else in the world decide the direction AI goes.
Is the aim of CC “…” text at the botton to prevent ai from using your comments or something? (I’m trying to understand.)
In theory, yes. I realize it probably won’t work, but it’s a momentary copy and paste, so it’s a low hanging fruit to give it a try, just in case it does work.
The terms of that license seem like a non-commercial AI would be just fine to use it, is that not intended?
IANAL, but I think its the citation stuff that would have to obeyed, which is far as I know bots today never give citation of where they’re modeling from when they post comments, so I’m hoping since they’re not citing they’d stop using.
I saw somebody else doing it, I figured it couldn’t hurt, one copy and paste and I’m done.
Typically the citation is included with the software, possibly linked from a site / service and/or included in their dataset repo (e.g. on huggingface.co)
True, but they still have to cite my name, and I’m not sure they’re going to name every person that they use every one of their comments to train their models from.
Granted it relies on them honoring the license, but still easy thing to try.
