Rather than this particular "magic" material, LK99, in the original paper(s), authors propose their theory on why this material is behaving the way it is. This is a totally new way for achieving superconductivity in room conditions. If it is confirmed to be true, scientist can try to create similar materials with similar lattice structures focusing on what's needed, rather than focusing on LK99.
Even if LK99 may not, one of the materials with similar properties they will create may be easy to produce and robust to use.
