I have not gotten fired for a bad report, but I certainly made mistakes in reports/Excel sheets that were intended as customer-facing deliverables. The good thing is that my coworkers checked my work and often noticed mistakes - not always, once an angry customer noticed my mistake, and my boss chewed out my
coworkers for being lazy. Obviously humans are not foolproof.
But if I was making mistakes, say, in 5% of my facts and figures...I probably would have been reassigned to other work. 5% is way too high for an Excel sheet: it makes the model completely useless. It often takes more effort to audit and fix 5% of busted Excel cells than it does to just rebuild the model from scratch. GPT-4/Copilot/Gemini/etc almost certainly make more than 5% errors for any real use case.
I am sure there are many bad organizations with lower standards than the organizations I worked at. My concern is that good organizations will adopt technology like GPT, inadvertently lowering their standards because they trusted a machine they didn't understand. It's very worrying that good people are rationalizing this choice by saying "well humans are also unreliable" without putting specific numbers to it. 5% errors in document summarization is not good enough for human workers, and it certainly shouldn't be good enough for software.
