something ive heard a lot about LK99 is that it will make chips not dissipate heat and i wanted to say: that is absolute bullshit!
roughly speaking there are two parts to a chip, transistors and wires, both create heat, LK99 would in theory be able to substitute* the current metal wires, but Tx is still gonna be dissipating
and now for the real kicker the * before, if you were able to substitute all wires with a superconductor you could increase clocks A LOT(think 50 GHz being easy), but you would need the minimum crystal size to be about 30nm for that, it is bigger which means you cant substitute all wires, and the ones where you really want it, the smallest ones are precisely where you cant do it
you can probably substitute bigger wires but the benefits there are paltry
TL;DR LK99 isnt gonna revolutionize chips
