This is the final frontier for privacy. It is no longer a matter of our control over exactly how much of our personal life we deign to share with the public — it is a matter of precisely how much of our internal existence is taken from us. If someone can manipulate our thought and emotion based on a stratum of data we willingly and unwillingly contributed to, then there is no real sense of public and private any longer — only an escalating series of intrusions.
Very interesting post.
