You could think 500 random internet articles - it doesn't matter. The assertion is still ridiculous. You literally will not be able to get a job as an accountant without being able to use Excel. Don't be an idiot.
You can also link to hundreds of articles showing that dynamic types cause errors. People don't care, they still use them when it makes sense to use them. There is no better mainstream alternative for accounting than Excel right now, period.
I think we agree...this site is indeed full of idiots confidently spouting nonsense. :-)
I'm not arguing about whether or not Excel is perfect, or if it causes problems, or if it makes demons fly out of your nose. I am educating you about the real world and how it's important to understand that no matter how "well akshually" technically correct you are, it doesn't matter at all if the advice you're giving is WRONG and not useful to people.
So, I repeat. Idiots confidently spouting nonsense.
