"The next 5000 days of the web"

I found Kevin Kelly's comparison of the web to the human brain fascinating, especially his statement that if the web continues to expand at it current rate, by 2040 it will “exceed human processing power.” His prediction that there will be this one “machine” that all electronics and people will link to, through their data and ideas, sounds like something straight out of science fiction, yet it may become possible. I don't really agree with his statement that as the web, the “machine,” grows and becomes more personalized, we the users and creators of the “machine” would need to become more transparent. My personal information is my information. Would it be easier for identities to be stolen in a completely linked and transparent society, or would the “machine” have become smart enough to recognize each individual by, say, their fingerprints or DNA when they attempt to purchase things, or create something? How would an individual stay individual in such a connected world?
