Can anyone answer this question about the potential impact of
room-temperature superconductors:

If I built a semiconductor with superconducting paths (assume we
figured out how to fabricate such things), would the resulting chip be
hard to EMP (ElectroMagnetic Pulse)?  That is, if the conductors
within the chip were capable of effectively neutralizing any applied E
field without undergoing heating due to the currents generated, what
remaining threat is there from the large and sudden E fields
associated with EMP?

So, do I misunderstand something about EMP or superconductivity, or
would this solve the (problem?) of building "hard" electronics?
