It's easy to develop a disconnect with the level that average users operate at when understanding computers deeply is part of the job. I've definitely developed it myself to some extent, but I have occasional moments where my perspective is getting grounded again.
HN has a long history of patronising the "average user" in the guise of paternal figures who don't realise that what they are doing is belittling the vast majority of tech users. I'm guilty of it myself. But they're capable of a lot more than we think they are.
Ultimately, it comes down to the willingness people have to learn new things. If they're curious enough to think about how things work, they'll be fine.
And weirdly enough, a Task like sorting a file with data in it, if you are not a professional, windows offers very if not non single way of doing this. You would need to understand file types, understand that csv can be imported for excel, you need excel, than you need to understand excel how to sort stuff in it.
The ffirst thing I do in Excel is select the pseudo table and click on table -> insert to make it a sortable / real table. I showed this to every one in my Team full of studied CS people because non of them knew this.
What do I want to do? "turn off my computer" What button do I press? "start"
