Are we all (on our way to be) Hell-Banned?

This day and age is all about personalization.
Custom search, news, ads etc.
In his talk at TED, Eli Pariser claims that we might be jailed, hell-banned from the world itself by a tailor-made smoke-screen.
Have we grown so accustomed to custom that our window to the world has become our own private show of Wag the Dog?

Are we going to need an error to save us from our perfect algo-life?
