The Bitcoin Legacy in our lives

We all (or at least a good part) know that bitcoin have a limit (21.000.000 Coins), but there are anothers coins that can become the "New Bitcoin", it maybe Ether or not (because better coins can came). But think about our Lives! Not your Day with eyes glued on a PC Screen, we are talking about Credit Card, Money and everything! did you ever thinked in a possibility of use Coins instead of Money? Thinking about it NOW seems like some crazy thing, but maybe in future we would not use money anymore. Bitcoin its really safe, now think about another coins security system? it will be near to impossible to get Coins By hacking. What do you think about it?
