I dont think this is the case. I feel like there just is a much wider gap because some people grow up without a computer (they may have one but not see the use of it) and others do. I bet you'd be surprised both at how non-tech-savvy and at how tech-savvy some genZ-ers are.
I have had people asking me for help because their "keyboard was capitalizing everything" (caps lock was on) or being amazed by touch typing.
But there are also many people who are (at least somewhat) tech-savvy and it's not so few people either.
