Yes, there might be more than one side to consider regarding modern technology. It is not necessary for "life" to own a personal home computer, to text or even to have a cell phone. Some may, or may not, be afraid of technology when they make such a choice, but many function just fine without it in their homes. btw, texting can be one of the most overused and useless tools in our modern society if one approaches it from a "gotta" put all my thoughts in other peoples minds". Because while it can be a good "tool" to text at times, it can also be a huge distraction and time waster for many. The older generation lived quite well without texting.
In fact they may have met the needs of many people better because they did not invade with "thoughts", but instead showed up at friends doors when they were sick, or they needed soup. The "old fashioned way".
Now, in saying that, some are quite prejudiced about conveniences of modern technology and they are afraid, and it is harder to learn as one gets older some concepts. But they have their reasons and it should never be judged.
It might make our lives more inconvenient to deal with such people who do not have the technology, but they choose keep their lives simple and in the manner they are entitled.
I happen to know several people in my circle who do not have a computer, or cell phone ~ both young and old. My daughter did not have a cell phone for the last few years. She does use my laptop and just started using her ipod for email when she was overseas.
My niece never had a computer or cell phone when growing up. She never went to school either. (Home schooled). At age 16 she studied and became a full pilot at age 19. Which requires tons of knowledge, math, physics, and managing modern technology. But she still does not have a home computer or cell phone. Land line yes.
Just my thoughts on what you brought up. It is not only the elderly who eschew use of computers or cell phones at times.
