I cringe at the tech issues I see daily regardless of age. They are mostly small things and not earth shattering but it proves that "digital natives" are not computer experts.
Example:I give them a link to something and I've gotten in the habit of making sure to just post news.ycombinator.com and not https://news.ycombinator.com because so many of them don't know you normally don't need to type https:// or a www.
I've said it to my wife so many times now it is engrained in her... we are driving somewhere (live in midwest). she pulls up phone and tries to do something on internet. when it takes more then 3 seconds she is like ugh what is going on. I have to say, honey let me tell you what is happening. Your phone is sending signals up to outerspace, bouncing around and eventually some data makes it's way back to your phone. Patience young padawan learner!
This isn't a generational thing. I know folks from all generations who have trouble with technology. Sometimes this is because things really are broken. It's not like a lot of things are high quality. Sometimes it's because stuff is hard to use. For those of us in tech we have a higher tolerance for learning pain and have enough understanding stuff is easier to pickup. For many others the UX is just painful to learn.
Poking at this as a generational thing can cause us to miss some other underlying issues worth paying attention to.
