The future that was once a dream may now be much closer

"The chemical composition of LK-99 is approximately Pb9Cu(PO4)6O such that—
compared to pure lead-apatite (Pb10(PO4)6O) —approximately one quarter of Pb(II)
ions in position 2 of the apatite structure are replaced by Cu(II) ions."

"such materials are vast and could bring about revolutionary changes in multiple
industries.
Among the possibilities are:
Much more efficient batteries
Quantum computers
Storage of renewable energy sources
Power and range leap in air, sea, and land vehicles
Super-fast magnetic trains
Increased efficiency in energy distribution"

I hope that safety is a concern from the start - like effects on life, the food chain, the environment, and quality of life. We don't need any more half-cocked technology that does damage because of not being properly vetted. It is impossible to consider every variable of course - even so we can do much better than rushing into something new that we eventually learn is damaging, and can be used by the ill-intended in harmful ways that may not have been anticipated.
