I don't think there's an easy answer to this. Operation would certainly be less costly.

The presence of the Planck's constant means that quantized vorticity is a consequence of quantum mechanics. h is very small, but so is m, so the ratio h/m is quite macroscopic. Therefore, superfluidity is a quantum phenomenon on a macroscopic scale.

Whereas even the most exact theoretical model will remain just a qualified regression of black box reality from this perspective. Unfortunately, as the Joe Eck example illustrates, the mainstream theorists have different priorities.
