I can't make such a conclusion as banks remain important to the community. We have to admit also that not all are crypto users, not all are adopting crypto and these banks give them away to secure their money. Maybe this will happen if we are not using fiat money anymore but, we still have and this still exists many years from now.
That even you see that the world is becoming strange, that seems far and not the only reason for such changes and put an end to banks services.
