A disembodied voice, digital ghosts and the contraptions we build that alter our humanity - Josie Long presents new short documentaries about machines.

We hear from the voice of Siri in the UK about losing control of what you say. Also - the story of a digital version of yourself outliving you and our relationship to the tools we build and the scars they leave.
