Also, Excel is just buggy enough to screw you over anyway, even if you’re trying to use it safely. I can’t count how many times valid formulas have failed on me across various instances of spreadsheets. Or I have to save, reload, or restart just to make things work. I’m constantly amazed by how much it’s used for business critical functions while being so routinely unreliable.
Most business people don't value and appreciate correct software. It's odd but shouldn't be surprising that most people are unable to effectively evaluate the risk of a software defect, especially in a tool like excel.
I don't think it's that odd. Marketing in general is the art of ignoring edge cases, focusing on majority tailoring. Why would I care about losing 1 customer due to changing our branding, if it gains me 1000?
This is why business is not considered a form of engineering, while software is (just barely). Imprecision is a tool in business, while in engineering it is an enemy.
