The way I look at it is a matter of attack surface and attack distance. Digital vastly increases both.

You have layers and layers of technology in even the simplest modern computers, and core network infrastructure subject to tapping or worse.

And much of this that can be done from anywhere on the planet.

Analog requires physical proximity, a strength and a serious inconvenience. But it also has the property of being legacy, in that you are now immune to state of the art digital methods, and susceptible to older ones that may be out of institutional memory and practice.
