When I told my wife about this, all she replied was how it's gonna be monopolized by big countries/big tech and our third world country like ours will never use it.
The materials and hardware required to make LK-99 are within the reach of a high school. It's really simple and doesn't require anything more than a very hot oven (hotter than a domestic one, but still very common). If it'd turned out to be a real superconductor anyone who wanted to make it could have done.
