I think that the world is not yet ready for the evolution of our currency from fiat/banks to digital currency simply because a whole lot of population still doesn't know about cryptocurrencies and like. I heard people talking from downtown about bitcoin is a scam done by some people to steal money. The world needs education about blockchain system, bitcoins, altcoins, how this works, and many more that should be important to know. I think that schools should be primarily the center of this education to the younger people so that the future of bitcoin will further evolve. If anything happens major to our world like multiple economic crashes on various countries due to fiat inflation, i think that people will come to work as one and be able to adapt to certain changes, like changing fiat currency to digital currency.
