This week on openDemocracy's podcast: is the present always changing but the imaginary future always the same? Writer Richard Barbrook talks to Siobhan O'Connell about his latest book in which the past holds the key to a more creative use of information technology for the future; and the true cost of your cappucino - we review Black Gold, a new documentary which highlights the exploitation of coffee producers in Ethiopia. Hear it right now, or download and listen later on your computer or mp3 player.

The music you can hear in this poDcast is "Modern Jazz Samba" by Kevin Macleod (incompetech.com).
