The last few paragraphs go kind of bonkers:

> The problem is a public as well as private one, and impersonation robots should be considered what the law calls “hostis humani generis”: enemies of mankind, like pirates and other outlaws.

> Improved robot detection might help us find the robot masters or potentially help national security unleash counterattacks, which can be necessary when attacks come from overseas. There may be room for deputizing private parties to hunt down bad robots.
