I've tried to explain why he doesn't need them. His response (about the security cameras) is always, "If there's ever a break in, I'll be glad I have them." The fact that actually using a light switch sets in motion a 20-minute repair via iPad doesn't seem to bother him. He doesn't view the wiretaps as a problem. He (with my mother's help) recently bought a wifi-enabled fridge and kitchen sink.
I love my parents to death, but it's ridiculous. I'm to the point where I usually leave my phone in the next room over when I'm not using it (and please check me in at a psych ward if I ever buy a smart-watch with a cellular connection and an omni-directional microphone). Its beneficial for clarity of thought / lack of distraction as well as for privacy.
Connectivity for connectivity's sake will be the death of freedom.
