it’s just a hypothesis, but they are saying that maybe the LK-99 samples people are making look like their figure 4 with tiny superconducting islands of lead That doesn’t mean we won’t be able to make wires and devices in the future. If it’s confirmed that we’re seeing real superconductivity (especially above room temperature) it’s going to drive a ton of research on finding actually good synthesis recipes to make continuous macroscopic chunks of the stuff, even if the current recipe isn’t particularly optimal
