The author's last key implication,
> Finally, and perhaps most ominously, the digital revolution has the potential for a pernicious effect on the very legitimacy and thus stability of our governmental and societal structures.
But they then proceed to say things like
> Will Western liberal democracies, already straining under the combined demands of decaying civil infrastructure, aging populations, upgrading militaries and so on, be able to afford these investments? Given that there is no specific forcing event to require greater resources, but rather a trend, history suggests that we will appreciate the seriousness of the underinvestment only when a crisis has occurred.
Meaning that currently, our system of government is simply not built to deal with modern technology. Yet they state that the fundamental threat of forcing change within societal and governmental structure is 'ominous', while at the same time implying that it is absolutely necessary.
Discarding stability and tradition for the sake of progress is inevitable, and will happen either deliberately, through policy (this rarely happens), or by revolution.
