An advanced persistent threat, one that is difficult to discover, difficult to remove, and difficult to attribute, is easier in a low-end monoculture, easier in an environment where much of the computing is done by devices that are deaf and mute once installed or where those devices operate at the very bottom of the software stack, where those devices bring no relevant societal risk by their onesies and twosies, but do bring relevant societal risk at today's extant scales much less the scales coming soon.

We agree.
