When you look at the issues going on the world many seem to be linked back to our tribal nature. Despite often utopian promises, they never seem to materialize. Whatever is proposed we fall back to our tribal nature. Perhaps its time to accept our tribal instincts and look at where technology help us live within those constraints.
Its very simple, groups of human tend to gravitate and work well in smaller groups where the same ideologies value persist. If others try to join these groups and not integrate to there way of life, they are rarely accepted and conflicts occurs. This is very much linked to our tribal nature.
The Blockchain allow groups (tribes) to cooperate as one system without the friction that can happen in forced integration. Nothing shows a better example that the current bitcoin public blockchain. There you have miners and nodes living in disparate parts of the world, adhering to different cultures and speaking different languages.
Just a thought...
