How do a superconductor and regular current carrying conductor interact?

Electricity tends to follow the path of least resistance, and superconductors have a resistance of 0. So I was thinking that if a superconductor was connected to GND and brought to a normal current carrying circuit, it should literally zap the circuit of it’s energy, since all the electrons will move through the superconductor rather than the simple copper wire. Is that the case, or would something else happen? And if it is indeed the case, how far away could the superconductor be, and would it work through an insulating medium? I don’t think dielectric breakdown should take place at low voltages, but the current in a superconductor would be practically infinite, so I’m not sure.
