It should be noted that an early, if not first, instance of a physical attack on a person has been carried out by the use of online means, in particular social media used to trigger an epileptic seizure. This concept has surfaced in science fiction, notably in Neil Stephenson’s Snow Crash (which also inspired the creation of Google Earth). In that case, persons are exposed to an attack while in virtual reality that causes them to become comatose.
With the Internet of Things, and the potential for projecting “force” (or at least damage causing light/sound ) over the network a new level of abuse and need for protection is emerging. One key in this particular case, and into the future, might be to have true identity disclosed, or as a criteria for accepting content over the net.
