In reading some of the back and forth posts both yesterday and today,
@boombox4, I think what
@michael hagerty and others are explaining is that much of the tech that you say is coming or will one day happen, is already here. Perhaps it's in a slightly different form than you envision it, but the fundamental capabilities are there and in some cases, have been for a while.
Smartphones are already capable of doing much of what you've predicted - and much more. Regarding TV watching at home, I have Comcast as my provider and I have no cable box. My TV is connected directly to WiFi and my TV is the control device, in does everything a more traditional "cable box" once did, so no need for a phone to act a as a go-between device for me to view something on my TV or act as a 5G "hot spot". If I want to watch video files from my laptop or phone, my TV connects to my computer or iPhone via Bluetooth. If it would become a situation where 5G would become the future for things like connecting TVs to receive and watch content, why not simply have the TV connect up directly to 5G as Michael implies, vs. having your phone act as a "middle man"? That said, I can alreadhy use my iPhone as a wireless remote to operate my SmartTV. "There's an app for that". All that tech exists. You say the "Wired House" will happen. I'm unsure exactly what you're getting at when you refer to a wired house, but the term "Wired House" was being used by Radio Shack more than 30 years ago when they already had modules and systems that would allow you to turn things on and off and control them from a push of a button next to your easy chair. The "internet of things" has existed en masse for consumers for a decade where one can set their thermostat, turn on their oven or stove, control their refrigerator, switch on or dim lights and view content from camera systems in their home, from anywhere in the world, so long as they can get an internet or cell data connection. The question. of course, is what level of comfort some people have with all that tech and how invasive do some feel it is.
Even with all that, cell phones are no more or less valuable to steal for thieves than they once were, and even if someone does take your phone (which you can track using various methods so you can try and find it quickly if stolen) that doesn't mean they can have access to the content on it, and in many cases such as banking and finance, just having your stolen phone in hand doesn't give thieves any level of access to pump gas and buy things with your $$, for instance.
