If you haven't worked on a business team, it's hard to fully describe the utility or importance of Excel. I think the best analogy for programmers is, imagine Vim if all the commands were easily discoverable through a GUI, and if everybody on your team and all the teams you work with also used it. Approximately any third-year (audit|financial|supply chain|actuarial) analyst will be able to fly around a workbook too quickly for an observer to follow along, and a lot of them will have custom commands and utilities set up. And those power users are using exactly the same tool as the person who point-and-clicks on every cell and button, so they can look over their shoulder and say, "You can just jump to the upstream cell with Ctrl+[" or "Have you tried using INDEX/MATCH for that?" I haven't touched a Windows machine for two years or been in an Excel-first role for five, but the muscle memory for the Windows-specific keystroke sequences for all the common commands is still there.
