I'd love some material targeted towards people like my aunt (spent the 60s and 70s programming then designing and integrating systems for hospitals, then the 80s managing cattle breeding operations with dBASE) and my father-in-law (PhD mechanical engineer who worked for the German equivalent of ANSI until his retirement in the early 2000s, very comfortable with Windows CMD) to deal with the slick, ever-changing "discoverable" interfaces the kids I babysat for are imposing on us with every app or phone update.
Does your aunt or f-i-l really need to know? I know older nerds who only use a smartphone for texts and voice calls, and who can't be bothered wasting time on social media. So far (anyway) "essential" apps like banking ones and government ones and "remotely check your home security cameras/solar panel output/etc" ones seem to be paralleled on the Web and accessible through a browser.
