My first language is Norwegian, and except for a few that I recall, I constantly have to refer to a website like this[1] to figure out what the hell they decided to call a function in Norwegian.

For a contrast: I use Copilot in vscode a lot. There it's pretty good at guessing what I am trying to do, and offering an auto-complete for it.
So mostly it feels like it's just helping me do the thing I wanted to do anyway, but faster.
But if eg a user knows how averaging of numbers works, but just doesn't know how to express it in Excel, even that example would be useful. I agree that if a user doesn't know how averaging works on a conceptual level, copilot won't save their butt here. (At least not yet.)
But this time "I just asked the AI to do the excel"
An Excel driving licence, mandatory for most white collar work, would be no bad thing.
