I’ve always subscribed to the “shared formative experience” model of describing generations. The description I always remember best is that the most impactful experience that separates Millenials from Gen X is that Gen X remembers getting their first computer at home but for Millenials there was always a computer at home, while the dividing line for Millenials and Zoomers is that Millenials remember a time before the internet and Gen Z doesn’t. Being more or less tech literate does tend to shift how we interact with some of these paradigm shifts, at least in my anecdotal experience.
Personally, I’m right on the boundary between Gen X and Millenial by this definition, as I remember my family getting our first home computer, but barely. That’s not really all that relelvant to the discussion, but it really does help me understand some of the fundamental differences between the various generations, especially as a boundary case that doesn’t particularly feel like I belong to either group. Plus, I work in at a community college with a bunch of Gen X and Boomers, teaching everyone from Gen Z to Boomers, so knowing what some of the most common formative experiences really helps me communicate better.
