Eric Schmidt and Jared Cohen say,

By indexing our biometric signatures, some governments will try to track our every move and word, both physically and digitally. That’s why we need to fight hard not just for our own privacy and security, but also for those who are not equipped to do so themselves. We can regulate biometric data at home in democratic countries, which helps. But for newly connected citizens up against robust digital dictatorships, they will need information and tools to protect themselves—which democracies and nongovernmental groups will need to help provide.

To me, this sounds optimistic about democratic countries. Authorities want control, whether they are in democratic countries or not.
