I definitely think that banks will disappear over time, it might be a while but banks are definitely a thing to go. Everything is moving online and we will have a different system of 'banks' maybe someone teaching another person how to utilize crypto lol
Banks also do the online thing so It think they will last for good. We know that bansk also growing, and it adopts new technologies like blockchain. Its a matter of time before all the banks adopt blockchain, and this will make them more stronger.
