I have one microphone near me, connected to the internet. The technology in the Dark Knight was novel to me. I was already aware of law enforcement remotely arming a mic on a normal cellphone at that time[1]. I am pretty sure fixed lines can be bugged in a similar fashion. As anyone who watched it with an interest in technology, I was fascinated by the pooling of microphones to generate a sonar like map of Gotham.
What struck me recently, as that was a piece of art, there are two possibilities (non-mutually exclusive). That the technology already existed and art was imitating life, or that people were inspired thereafter to create the technology and life was imitating art. Certainly both could be true and
I'm willing to entertain a third possibility that noone bothered, but that seems unlikely to me.
