Imaginary numbers are indeed poorly named. They are not much more imaginary than members of ℝ.

    It's all fine... except for the part where reality has a √-1 component.

    Well, in AC circuits, having √3̅+√-̅1̅ A of current makes as much sense as having 2 amps with a 30° phase shift. It's just easier notation for calculations - Cartesian coordinates for what would otherwise be polar.

    That's BS notation. If you want Cartesian, just use 3i+1j, no need for some impossible √-1 that you then redefine some operations for, just so it becomes orthogonal to R.
