When I explained to her the potential if it truly was the breakthrough being reported, her first reaction was:
"I hope we establish a government agency to regulate everything floating around because I don't want to get bumped into by random stuff".
It's a point, but well human need to push the limit, no matter what.
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.
The pure LK-99 crystals pictured in the article were obtained using more advanced technique: "Unlike previous synthesis attempts that relied on crucibles, the researchers used a technique called floating zone crystal growth that allowed them to avoid introducing sulfur into the reaction, eliminating the Cu2S impurities."
But I agree that if there's money to be made, it will be available world wide quickly.
