Needpedia is about sharing ideas and forming consensus and agreements. But most people don't presently know how to do that, in fact they've essentially been trained to think in terms of labels and judgement. So even with the best technology on Earth, peace may not be possible. 

Particularly in the minds of most people, who think psychology just means you become a psychologist, or a con-artist or something. They don't yet realize they could transform their own lives, they've never seen anything like that before. 

For anyone not already familiar with Rosenberg's NVC, I highly recommend a workshop posted to Youtube here. 

NVC layers may well come to be the single most important aspect of this project because they enable large numbers of people to not only discuss the world's most important ideas constructively; they'll enable them to see the rest of the world differently. NVC is so powerful it will change the relationship, you have with yourself! Because you'll see yourself becoming capable of more things, because it is simply more practical to understand the world in terms of needs. 

Could you imagine a world of people who all know how to break controversies down into the language of needs and observations? This runs deeper than technology.
