I like how the GenX and millennial is the only example that isn’t overwhelmed at first. I think it’s definitely worth considering that those particular generations have a significantly greater ability and openness to learning new paradigms and adapting to new UXs, because that was something that was unavoidable for all of our formative years.

Due to the rapid pace of technological advancement from 1980-2010, it was simply necessary to adapt to brand new systems and interfaces every few years. And the rewards for doing so were enormous, so we naturally learned that if you took the time to figure out these new technologies and interfaces, you would be rewarded with much greater capabilities. For previous and subsequent generations, that process probably didn’t shape their way of interacting with technology as much, so they’re reluctant to put in a significant amount of effort in learning to use new technology.
