Public Enemy frontman Chuck D has a pessimistic scenario about the future of technology. The politically active rapper tweeted last night, "2013 we will see the end of SocialNetworks. 2012 every phone is a tracking device & keeping you locked in CRIB."

Chuck D has a long history of engaging with technology as a positive force. He testified before Congress in support of peer-to-peer MP3 sharing at a time (2004) when many other artists were vehemently opposed to the practice. Not to mention all the sampling and remixing and looping that went into the music that made him famous.

So, you can't write Chuck D off as a Luddite for his worries about social networks and phone tracking. He likes technology (another example: his prolific tweeting) but something about the invasiveness of this particular set of technologies puts him off.

All I'm saying is: when the man that wrote "Fight the Power" turns on you, it might be a good idea to reevaluate what you're trying to do. People like Chuck D could be the beginning of the mainstreaming of privacy concerns.
