If the app can be replaced by a website the app is useless. The web is not as powerful as an app and you will miss out on emerging tech. Facebook doesn't actually need an app, but I can not unlock my door, tap to pay, or connect to a specific selection of speakers in my home on a website.
100% of the emerging tech you listed either allows for a hacking / warrant / data leakage risk or is else so decadent I don't know how to respond. I don't want any of it.
Then all your interactions on the computer in your pocket that is more powerful than the computers that took us to the moon are just a bunch of JSON and REST calls. I will locally map out my home in 3D for renovations while you let social media dictate how you use your computer.
