A few practical things that we need superconductors for which currently require very expensive cooling:

1) MRIs — could be way cheaper, smaller and more ubiquitous with room temperature superconductors 2) Maglev trains — superconducters expel a magnetic fields that can make things "levitate" (called the Meissner effect). Maglev trains have minimal friction and are incredibly energy-efficient. 3) Quantum computing — most designs require cooled superconductors. Room-temperature superconductors are a requirement for future portable quantum computers, or quantum chips that sit side-by-side in conventional computers

There's a ton more implications, just think about how everything from electric cars to smartphones was only possible due to modern batteries — that's the scale of technical innovations that could be built on this.

MRI is a potential application of room temperature superconductor in general, but not specifically for LK-99. One disadvantage of LK-99 is that it has very low critical current, see patent figure 10.

On the other hand, 300 mA is more than enough for computing applications.

We are still at the if-it-is-real stage. I would not take any wagers that the generation one release is indicative of an industrialized product performance.
