I wonder where that "human accuracy" statistic is coming from. Plenty of people don't know how to read and interpret data, much less use excel in the first place. There's a difference between 1/4 of people in the workforce not being able to complete a task, and a specialized AI not being able to complete a task. Additionally, this is how you get into the KPI as a goal rather than a proxy issue. AI will never understand context isn't directly provided in the workbook. If you introduced a new drink at your restaurant in 2020 AI will tell you that the introduction of the drink caused a 100% decrease in foot traffic since there's no line item for "global pandemic". I'm not saying AI will never be there, but people using this version of AI instead of actual analysis don't care about the facts and just want an answer and for that answer to be cheap.

Depending on where you go to school, 70% is passing while 50% is not. While "not far off," one is a C, the other a F.
