I think were rapidly heading towards a cashless society . I also think there will have to be a fundamental shift with respect to the way currency works. There are all kind of theories as to what will work, Universal Basic Income etc I think the basic problem we face with fiat is the tendancy to hoard and therefore there be a lack of liquidity. Were in a situation were the top 5% odd own as much as the bottom 95 % . That will have to reset at some point.
