When the Beverly Hillbillies struck oil on their land, they instantly knew they were millionaires. Finding oil was, and still is, the equivalent of finding an Aztec tomb filled with gold and jewels or winning the lottery a hundred times over.
But the world is changing, and there's a new type of fuel to run it: Data. "Just as the politics of oil shaped the 20th century industrial economy, so the politics of data will shape the 21st century digital economy," writes Andrew Keen through CNN.
We're in a digital economy where data is more valuable than ever, and it is the key to the smooth functionality of everything from the government to small ad agencies. Without it, progress would halt.
The European Commission Vice President for Justice Viviane Reding vs. Facebook Chief Operating Officer Sheryl Sandberg
At this week's Digital Life Design (DLD), an annual technology conference in Munich, Reding and Sandberg discussed access to data and all the privacy and control issues that come with it.
Reding argued, "the great threat to individual liberty in the digital age comes from companies that use our data to enrich themselves -- buying and selling our most intimate details for their own corporate benefit." She calls for tighter legislation on what companies can do with data and how they can access it.
"To this end, Reding is introducing legislation which will give consumers the right to be forgotten on online social networks like Facebook and Twitter," reports Keen.
Sandberg takes a different approach. She calls the digital revolution "a really big deal." She claims we increasingly identify ourselves with our online presence. "Above all," continues Keen, "it turns all of us from being passive receivers of other people's information into active broadcasters of our own lives."
