If I get a check I can cash it in an ATM or with my phone. I can transfer money between accounts, open accounts without ever going into a bank and got a car loan from the credit union I would have gone to otherwise from the car dealer.
My local bank had a great deal for interest on savings, but you had to be in an area without one of their branches. If you had a branch nearby you still got the 0.1% rate.
Bank branches are an expensive antique.
I personally don’t feel comfortable banking on line or by phone. Too easy to get hacked I should think.
