Calling it "smoke and mirrors" sounds weird in my ears: they have
merely automated what you would have done manually to reach the
same level of precision otherwise.

The main difference is that the 3458A *also* gives you a very
fast data-collection/digitizer, which, instead of being calibrated
by twisting trimmers, is calibrated using the same math as is
used for the metrology grade instrument in the same box.
