Really??? So if I connect two (super)capacitors in series, thereby doubling the voltage limit, I have somehow squared the energy storage!

You've also halved the capacitance and doubled the volume. So: twice the voltage (4x), half the capacitance, (0.5x), and twice the volume (0.5x). Looks like your energy density didn't materially change.
