Why specify just "newer generations?" I do tech support for older generations in my family and they're just as un-tech-savvy.

The vast majority of people don't care how a computer works, they just want it to work. And that's fine. There are lots of machines and other technologies in my life that I can't spend the time to fully comprehend, I've got other stuff I need to do. As long as there are a few people who focus on each kind of machine and each kind of technology then civilization carries on okay.
