> You know what happens with Excel. Karen from accounting builds a “simple” spreadsheet to track expenses. Six months later, it’s a 47-sheet monster with circular references and VLOOKUP formulas that would make a mathematician weep. The company depends on it, nobody understands it...
It sounds like Karen did a valuable service to the company. She combined a technical skill set with her domain knowledge to create a system that was so successful that the company now depends on it. Cleaning up the technical debt seems like a task that's well worth the cost.
> ...And when it breaks (not if, when), guess who gets called to fix it?
I'm not sure, honestly. It depends on whether you want the fix being done by a resource you consider to be a cost center or a value center. The former will do the cleanup job for bottom dollar. The latter would team up with Karen to amplify the project's impact while cleaning it up.
For these reasons I think your analogy is not effective. I don't disagree with your thesis, though; I prefer code in almost all cases. But that's just me. I know for certain, though, that if I had stock options in that company in this hypothetical scenario I'd rather keep Karen around than whoever fixes the VLOOKUP syntax. And if visual tools are what empowers Karen... well, there you go.
