This is a very interesting point and I can see it throughout zoomer culture when it comes to the down and dirty technical stuff, but I think there's a distinction to be made between being technically apt and being able to grok whatever the hot shit consumer-grade tech paradigm is right now.

In the former context, a lot of zoomers have already "failed" but that context is the territory of people who reach out to learn it - in other words, the nitty gritty tech stuff will always be for the technical types. In the latter context, I imagine millennials will probably mostly be fine and zoomers will, too. I say "mostly" because we're already seeing millennials start to kind of skip the latest trends (TikTok comes to mind immediately). Zoomers are already coming to grips with not being able to understand Alphas sense of humor via memes. Whatever the next social media platform is, I imagine it'll be primarily a home for Alphas, leaving zoomers and millennials where they are.

Will there be spillover across the board, with members of different generations populating the other platforms? Sure, there are always exceptions.

As far as physical tech goes, like how millennials got the smartphone and zoomers grew up with it? It's highly dependent on how ingrained it becomes in society. Hard to exist without a smartphone these days, so everybody has to know how to use one. Boomers have more trouble because they got it later, but there are plenty of them who are just fine with current phone tech precisely because they need to be for professional AND personal use.
