You don't think that there is room for a new high-tech bank to step in and eat the lunch of the big banks? If you started a bank from scratch, built with modern technology, you could provide all kinds of valuable services and adapt to change much more quickly. Pretty much every service provided, particularly on the web, is some application that screenscrapes CICS screens or reads data from VSAM. These applications a tricky to build and take much more time than they should.
