For this time anything can happen. but I think that the world will switch to another payment system, the world financial revolution will take place 
To me that is too soon, I also believe that the current economic system cannot last forever and it is going to fall at some point during our lives, but banks are getting better at manipulating the system and at deceiving people and make it seem as if everything is okay, so in my opinion we are going to need a few decades before what you predict will happen.
