My grandpa programmed and downloaded movies and books via torrents even when he was 86 so I don’t think it’s an age thing, it’s kind of like she never thought it’s worthwhile to understand so she focused on other things. However, I can tell that it’s going to be really overwhelming for her to start programming without knowing what it means to e.g write to a text file via a script, or how to search for things properly, even how to use the internet securely. If there’s something like “computers/your OS for dummies” and someone has experience with it, I’d be grateful.
