After many years of work, why do you think it's necessary to have a change of job? For the same reason you have issues with younger people being as good as us or even better at typing / working with computers - getting tired of repeatedly doing something. The fact that you can't switch from our old interface habits says a lot there.
For the kids the computers are new, they're excited with them and learning / adapting very fast. We know computers for so long already, we're tired of them. That simply. Time to conquer new areas
