Yesterday Mark Zuckerberg said that someday he thought computer networks would be connected right into our brains and we would communicate to our friends through thoughts.

I predict if that day comes, we will have no friends, in short order. I've had the experience where I relaxed so much that I just blurted out a weird thought that was in my head. It always ends badly. You have to have those filters. Otherwise we'd all hate each other all the time.

I suspect that by the time such a thing is technically possible people will value the opposite. Give me a feature that puts up a nice wall between me and the random thoughts of everyone else. I already feel that way sometimes, on Twitter and Facebook, and people still (mostly) have to type their ideas through their fingers to get into other people's minds.
