> People filtered in the past by what they cared about and who they spoke to. Now much of that filtering and indeed much of your friends are algorithmic suggestions.

But the suggestions are based on what you like (or what the algorithm "thinks" you like), and I don't believe that we're converting communists into libertarians because Twitter says "other people you might like: ".

The process is very similar but has gotten gotten much more efficient, because you're not limited to the people in your immediate vicinity. You don't need to move to a big city to find other people who think like you. The world has become a village, and you can now connect with your ideological doppelgangers around the world from the comfort of your home.
