In my family, my parents’ generation either worked in IT and spent some of their careers writing macro-assembly on punch cards, or they have no coherent answer to the question “what is an operating system?” For this latter group, I’m going to be their sysadmin either way, and I no longer sysadmin Windows.

Everyone in my generation are pretty computer literate; I think I program in the most languages but my cousins all know what file systems are, could put together a household budget in Excel, know how to install software etc. A few of my cousins are in that “mostly use Windows for gaming and Ubisoft/EA aren’t great companies” phase where Linux is still a bit inconvenient.

My niece, the only representative of her generation in my family, has a reasonable child’s grasp on computers. She’s used iOS and ChromeOS and Windows and Linux, so I’m pretty sure she understands the same hardware can run different software. Not sure how deep that understanding goes but she’s a kid she has time to learn.
