Not sure luddite is what I would call it in this instance? I think practical is a better term. My parents have a 70+ year old house. The bell on it, is whatever the builder put in. Still works. Adding complexity adds maintenance. Some people like that. Some dont. I could whip up some very nice decent IoT system for my doorbell, camera and all. But I leave it as a button. The next person to own this place will be glad I did.
