No, there is a good basis for this. It's not their fault, the technology they learned to use didn't involve troubleshooting or managing the system. There will always be some who understand, but most Gen X and Y are competent on computers. The same cannot be said for Zoomers.
That's a terrible bar for who is tech savy. I can guarantee Zoomers, on average, are far less competent with technology. It's not their fault they grew up with apps and iPhones.
