Not to simplify the issue, but in general people are resistant to change, especially imposed change, regardless of whether it’s good, bad, or indifferent. And the older one gets, in general the more resistant. Why? Because as we get older, we’ve found ways of doing things that suit us, we’ve been doing them for a long time, and that builds up inertia. This is a direct application of Newton’s 1st law. Yes, they apply to people as well. If you’re going along, minding your own business, and someone or something tries to change your direction or the way you’re going, they or it needs to exert greater force than for someone who is younger. As we age, we develop more inertia or resisting power.
Ever notice that a child can often pick up something faster than you can? Here’s an example. My 5 year old grandson handles the TV box remote like a pro. He knows how to find his TV shows in the list of recorded TV shows and how to start and stop them. He got that with minimal instruction by watching his father and because it was something he wanted. How long did it take you to understand yours? Probably longer because you had to read the manual and then assimilate the information. Now what happened if you changed remotes. A great many people wouldn’t bother changing because there’s not enough gain.
New technologies usually take root in younger generations. They may or may not be accepted by older generations, but it doesn’t matter, because eventually, the younger generations will replace the older, and that once new technology will be just the way things are. And the cycle will repeat.
