Yes. plenty of articles coming out about how many in gen z are technology illiterate. I am started to see it at my workplace since we hire a lot of fresh college grads. getting more support calls for completely inane stuff that shows the person has zero basic technological knowledge, like the type of stuff that my you see from boomers. and often it's the issue is simple the user doing things wrong and refusing to understand or learn to do them correctly, like a boomer.
it's wild to think a 22yo is incompetent at basic computer skills, but like you said, all they do is social media crap on their phones. they have no idea how to actually work with PC/Mac applications, let alone solve basic problems or change settings.
