You bring up a valid point. I believe blockchain will have incredible benefits for humanity. Hell, it already is. However, that does not mean that there will not be problems. I am a believer in technological unemployment and that technology is moving ahead so quickly that it will outpace any job growth that newer techs creates.
There are many arenas where the blockchain will penetrate. Financial, medical, and government are just three areas where major disruption will take place due to the implementation of blockchain.
