I sort of see where you're coming from, and it's probably correct that processes that rely on complex spreadsheets would often be better served by well engineered and designed software. But that is often not the realistic alternative .

The realistic alternative would be a mess of poorly engineered custom scripts, which offer no advantage over the spreadsheet.

With the spreadsheet, anyone can take out their calculator and check the results, without knowing any programming. That's really the killer feature.
