> All deterministic software does this. That stands to reason, yet much software is decomissioned or replaced every year. All of it deterministic software. Perhaps the software is expensive to maintain or use, doesn't adequately meet the needs of the business, is error-prone, or any one of a million reasons. COBOL works at the heart of our industry and our society, despite COBOL being an ancient crufty language. In the same way that may of us never see our hearts or become heart surgeons, I may never meet a COBOL program or a COBOL programmer. I am still thankful they are there, and I recognize they serve a function other software likely would not.
