Someone here once told me of how Microsoft had these customers who pay $$$ so a real driving force in the development of Excel are these horrific, unspeakable, monstrosities of spreadsheets critical to the operations of some very serious companies, serious bookkeeping, serious material operations. The elderich horror spreadsheets are decades old, have 100,000s of rows, spaghetti code formulas— Microsoft always checks updates will not harm them. IDK. if it was true: but it *felt* true.
