So I've had this idea, and wanted to just share and discuss.
 
With tech that we've seen recently like Google Glass (lol) and smart watches (yes this was an idea that came from the just uploaded video), and in addition to this, Apple, and namely Google taking an interest in AR technologies; a wearable/smart glasses combo doesn't seem far off.
 
So my idea, is based around AR Glasses, and a Watch or wristband or rings.

The glasses would provide a HUD, but the main purpose would be displaying the watch's holographic interface, yes, exactly like the sci-fi hovering display, except only you can see it. 
This still keeps the privacy of a traditional phone, because only you can see your display, interactions can take place with swiping/gestures and typing would be on a projected keyboard including wrist tracking.
 
This could be take care of by instead of the watch being any kind of standalone device, you wear two rings or wristbands that serve no purpose other than to provide tracking, acceleration and gyroscopic information, the data could be processed either in the glasses, or, solving the bulky glasses issue, you could still have a regular phone, but this whole get up is just accessories, much like VR is to video games.

The more I type the more outlandish this gets, but, I wonder if anyone else has ever had a fleeting thought of something similar?
 
TLDR - Google Glass (but better) with hand tracking rings/wristbands for that cool sci-fi holographic watch, but it still keeps your stuff private like a normal phone (and is more feasible with current tech).

Yeah I think that's where we are headed anyways. We are already seeing stagnation with phone demand with companies simply adding more cameras and now folding phones. Apple is set to release AR glasses in 2021 or 2022 I think. Hololens has been out for over 7 years now and Samsung demoed it's new AR glasses to come out next year. I think they will use the phone as the hub for processing information and then when we have 5G everywhere and Starlink we will offload all the computing to the cloud.
