One should always consider the positive and negative uses of new tech. It always lends power to both aspects. My biggest fear from block chain and really every technological tool, is if it becomes controlled and used only by the state on its citizens. For example cameras on every street corner is a really disturbing notion for a free society and way too 1984 Orwell. Then you consider police officers can also be seen with electric eye and undeniable corruption exposed. I honestly think the police fear public cameras much more then myself and I am certainly an outlaw of sorts but have no shame in my actions, public or private. Not because Im shameless but because I feel I am a fair and respectful person with no intention of offending anyone. If block chain and internet freedom were taken away only to be used for state purposes, it would be a strong tool for dystopian authoritarian society. It sounds eerily similar to the number of the beast in biblical prophecy. Honestly we are at a very pivotal time with this technology. If we are able to freely innovate BC it will, without doubt, level the playing field in ways humanity has never experienced. The power structure and direction of progress will be in the hands of the many. We could for the first time in human history have a democratic election and finally your vote was counted verifiable and accurate. It could really be the defining era of the transition to the age of Aquarius. The Aquarian age is supposed to be not only an age of massive technological advancements but also one of great Humanitarian transformations. I hate being extreme because I really enjoy the middle ground most often, but if those that are benefiting the most from the current system of wealth extraction, realize their days are numbered, I'm not sure what they might be willing to do to preserve it. It would take some extremely drastic situation to restrict the worlds use of the block chain. Well I know what world I want to help manifest. Hopefully see you there!!
