Well, except for in particle accelerators, stars, and supernovae, atoms are never created or destroyed, so if they're creating gold, it's here for good.

Except that everyone with a fusor can feed the gold atom a neutron which converts it to unstable Au-198 that decays to mercury. Fun times when you can (theoretically) transmute gold to mercury with stuff you can order on the internet.
You could do that for decades already!
It just doesn't make a lot of economic sense, but I wonder why nobody made fusion art yet.
I definitely will mis-speak/mis-write, but my mathematic (also flawed) tells me that if Gold + 1 = Mercury, then Something + 1 = Gold, so we can find that "something" add 1 of the thingie, and booya!! gold!! (right?) (please read the above with silly humor)
In a slightly more serious note, I remember listening to Elon in some podcast 1-2 years ago saying how they create new metals/alloys that nobody had created previously, because they needed specific needs covered, and no known material had the attributes they needed. So.. in a way..
The whole concept of "turning lead into gold" is somewhat self defeating. Because turning lead into gold doesn't make lead as valuable as gold, it makes gold as valuable as lead.
This has happened before. Aliminium used to be very scarce, and hence expensive. More expensive than silver. The top of the Washington monument is capped with aluminum.
A new process was invented to extract aluminum. So scarcity disappeared and value is negligible. Today we use it for packaging soda.
Turning anything (cheap) into gold means gold is cheap. It doesn't make us all rich.

Comparing a slight tweak to the mix ratio of 304L stainless steel alloy to transmuting elements is a stretch...
The same mechanism that lets you convert gold-197 to mercury does in fact work to convert the equivalent isotope (that is, 1u lighter than gold) of the element left of gold on the periodic table to gold.
The only problem, the element left of gold is platinum, and platinum-196 is not even the most common isotope of platinum, making up ~25% of it. You're rather unlikely to be able to make money on this.
(Not that you would have been able to regardless of the price of platinum. There are 3,000,000,000,000,000,000,000 atoms in a gram of gold, and a desktop fusor is going to generate ~<1m neutrons per second.)

Wouldn’t that be platinum?
Just saw this idea recently -- to add to your list: "Magnetars’ strong flares forge gold and other heavy elements" https://earthsky.org/space/strong-flares-magnetars-forge-hea... "After black holes, neutron stars are the densest objects in the universe. A neutron star forms when the core of a massive star collapses during a supernova explosion. Intense gravitational forces compress the core, reducing most of its elements to subatomic particles called neutrons. And magnetars are neutron stars with intense magnetic fields. On April 29, 2025, astronomers said a powerful flare unleashed by a magnetar, named SGR 1806–20, created large amounts of heavy elements including gold, strontium, uranium and platinum. They think magnetar flares could produce as much as 10% of the heavy elements in our galaxy."

I have no clue about this stuff, but don't black holes also change matter... somehow? I mean, with all that gravity and stuff, crazy things must happen in there, right?
What happens inside a black hole is basically unknowable. We can only ponder the math which leads to ideas like space and time swapping roles once you cross the event horizon.[0] The only thing that comes out is hawking radiation, which is sort of like... half of nothing.

> space and time swapping roles once you cross the event horizon
This is a common misunderstanding. Space and time don't swap roles. It's just that there's one rather popular coordinate system (Schwarzschild coordinates) whose coordinates t, x outside the horizon correspond to temporal (timelike) and spatial (spacelike) directions, respectively, and inside they correspond to spacelike and timelike directions. What we mean by "timelike" and "spacelike", however, does not change.

Kind of a one way path though - unless you count the gamma radiation and split pairs. I'm no expert either but it's pretty cool stuff.
As I understand contemporary physics, once matter crosses the event horizon it becomes part of the singularity. The singularity behaves as a single super-sized particle, so nothing happens inside. However I also have heard that many physicists don't believe that singularities actually exist, it's just the best mathematical model we have for physics that are too extreme for us to measure.
It does not become part of the singularity once it crosses the event horizon. The event horizon is actually rather uneventful as far as any particular piece of matter crossing it goes - it only means that this matter can never leave the boundary defined by the horizon, but it doesn't change it otherwise. The singularity (if it even exists) is the thing at the center of the black hole, far below its event horizon.

>> it's just the best mathematical model we have for physics that are too extreme for us to measure
It's not only a measurement problem. Rather, the laws of physics, as we currently understand them, lead to this singularity. Sure, many physicists may doubt the existence of the singularity. They will need new physics, not only better equipment, to challenge it.
Particles with any (rest) mass can have lots of things that happen inside.

Radioactive elements probably have something to say about that.
