As Far as I'm concerned, The fourth industrial revolution make people's life easier because robot will replace people to do many things. It means that people will do less than ever. Bitcoin have function to help people to save time for payment. It tries to make A' cashless society' for human life.
The fourth industrial revolution already happened.You are talking about the fifth industrial revolution,when the robots and A.I will take over the human civilization.This will make people's life harder,because it will make everyone lazy and dependent.Only the smart people will survive.Stupid and uneducated people will die from poverty,because their jobs are taken by the robots.
Maybe bitcoin lead us to fourth Industrial revolution. But its bit harmful for us being involve with fourth Industrial revolution mean not to do work with your hand and give command to robots to do your work which mean you can become laziest person.
