IoT is questionable...
Maybe not right now since it's in it's infancy. I'm not a Ludidite but I can visualize what will happen. Couple "A" buy a new house with all new, built-in IoT.. appliances, power, everything imaginable. They get a pile of manuals and have to have it set up with a wifi router (maybe 2 or 3 even for coverage). What happens when the IoT things start breaking? Or dying? Or they need new router(s)? Will they still have the documents? Will things be able to be repaired or replaced without having rip open walls, toss major appliances?
Some years down the road, couple "A" sells their house to couple "B". Did couple "A" keep all the manuals on the equipment? Do they even remember what they have? Couple "B" moves in... new router(s)? Re-set everything up?
Maybe by the time these things become as ubiquitous as a ceiling light, it may not be a problem. But having bought a 30 year old house, I'm finding problems getting regular things serviced. Companies out of business and no replacement parts, or newer models and the old ones are now junk. What was 'in code" isn't anymore. Will we be creating problems or solving them with IoT?
