@Steve Dekorte Programs and apps are historical accidents. They are subelements of computing systems, but it’s only the system that matters in the end. A Spreadsheet is such a system. A system necessarily includes code and data, in some form. Focussing on programs means neglecting the data.

Well said. I wrote along these lines in https://shalabh.com/programmable-systems/systems-not-programs.html.
