True, I started as a COBOL programmer (did a lot of TELON online screens, JCL, CICS, DB2...) as my first job in 2009, for a biggest retailer - personally it taught me a great deal of software engineering - having a background in electronics engineering helped I guess.
The whole stack, and the complex business built around it over many years makes it so difficult for these large institutions to port their solutions on to a new platform in my experience too.
For a lot of these companies, these backend systems on Mainframes just works and I believe there isn't a proper incentive to move on to a new platform anyway.
