Its a material that basically gives electrons "inertia" which acts like an inductance derived from magnetic fields. There is a time constant to it, which determines at what frequency range it starts contributing to the inductance value.

To make it useful for power electronics they would have to push out this time constant by at least 4 orders of magnitude, I don't believe the theoretical material properties support that.

You might see this shaving off a few mm^2 from RF ICs and providing better RF performance. Applications in power electronics, where inductors take up the most volume, seems unlikely.

On the flipside, kinetic inductance detectors (https://en.wikipedia.org/wiki/Kinetic_inductance_detector) for astronomy have been around since ~2000 and in the low light single photon regime they have much less noise on readout than photoelectric detectors (CCD/CMOS/etc).

Perhaps power electronics will move to higher frequencies, too.

Will have to drive gate and source capacitance down a few orders a magnitude to make that a reasonable trade-off.

They just did thanks to GaN transistors. The limitations in power electronics generally aren't the inductors.
