Not at the current state. People are still dependent on banks to have access to paper money, because there are few places where you can get this through Bitcoin ATMs. In addition, there are few places where you can spend Bitcoin directly.
I would definitely agree with you. bitcoin can not disappear banks at this time nor in near future. because lots of people still don't aware of bitcoin and lots of people are know about it but don't want to use bitcoin as their primary money and payment system.
so it is hard for bitcoin to disappear banks.
