There is no "GenZ rejection of the digital world" thats a marketing narrative. Gen Z is overwhelmingly online and the handful that do reject it are no more than a rounding error.

Using it because you're practically forced to use it, is not the same as not rejecting it intellectually. While that's probably still a minority, it definitely seems larger than just a rounding error to me.

I've seen, though rare, other people with dumbphones, for example. And more people who would like to have one.
