Slightly confused here.... aren’t insulators used to separate conductors? What good is a material that conducts, as an insulator?

“It goes far beyond what ordinary matter can do”
Not sure how, myself. They seem opposite properties to me.

Think of a switch. When off, the air insulates the lightbulb from the voltage.
When on, it conducts.
Now think of semi-conductors. Normally insulates but with an applied voltage, become ‘switch on’.
Now think of a ‘wire’ that is an insulator that when pressure is applied becomes ‘switched on’.
Only now that ‘wire’ is a superconducting wire!
