I don't think this is a foregone conclusion, and it's easy to say this and sort of throw your hands up and go "oh well, woe is me" but it's kind of a cop out, no?
I have family in their 90's who can navigate whatever tech you put in front of them, because they think it's important to figure things out when they get stuck. My father can barely turn his phone on because at the slightest frustration he gives up and waits for someone to "fix it" for him. Certainly different folks have different aptitudes, but choice and working through things plays an exceedingly large role.
