I think the watch + AR glasses/contacts will be what they move to. The same way the watch is now tied to a phone, the AR glasses will be tied to a watch.
I wonder how compact AR glasses can get, near term. My wife and I just gave our Oculus Go to our grandson and bought an Oculus Quest which is portable, has a sort-of AR ability because of external lowers video cameras, and is comfortable. But, the Quest is a long ways away from glasses.
A little off topic, but I worked in VR in the mid 1990s for SAIC, and Angel Studios/Disney. I am so very happy to see inexpensive consumer VR rigs like the Quest. Some of the media produced for the Quest is very good, Vader Immortal being my favorite entertainment ever.
