Just going for it and fucking up over and over really is the best way to learn how to use computers... I was lucky enough to go through that as a kid/teen so the consequences were pretty meaningless.

I need to start faking computer illiteracy or at least downplaying my level of literacy. Employers notice how quickly I get computer-related tasks done, but then they expect that as my norm while my coworkers are struggling to use any device without a touch screen.

The last new hire I trained was in his mid-twenties and lacked basic tech literacy outside of the iPhone. I asked him to write up a quick protocol using a template I sent him. He typed the text of the Outlook file preview into notepad and went from there. I was baffled.

That's the youngest I've heard of someone like that. My grandpa was like that and in his 90s and I still thought he should get a computer for at least banking and stuff.

She must have been in her mid 40's when the iPhone came out, that's young enough to be interested and learn about the tech. She must have just actively ignored it or refused out of principle or something.

She actually sounds like a treasure. Guide her well, and learn from her what you can.
