It’s not just younger Gen X. I’m oldish Gen X and loads of us were programming computers for fun from the late 1970s on. By the early 1990s you couldn’t really avoid computers, and you couldn’t use them without at least a basic level of understanding. By that time many of us had been using them for a decade or more. It’s those who grew up without computers (before they became common) and those who grew up with iPhones that have a problem with tech.
