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.
