Telltale contrails. Discuss
BOSTON, USA – When a plane crosses high up in the clear sky, it sometimes leaves behind a trail of conensed vapor, called a contrail. Some days, you can look up and see contrails crisscrossing the sky, revealing patterns for those who know how to look for them.
For a long time now, our mobile devices have been watching us and, in some ways, leaving a contrail of our paths behind us. This contrail could be broadcast by the various radios the devices carry, or by some app communicating continuously (or even intermittently) to some box out in the Cloud.
A recent article (see below) got us wondering how far we want to take this permission we give devices to leave these trails.
