As anyone who's used it knows, CB radio is very much unlike anything you can do with a smartphone[1][2], so I argue it should go in the second list at the end of the article, where the author talks about things that can't be replaced by a smartphone.
[1] notice how CB radios can still be bought at major retailers such as this one, one of the largest in my country https://www.supercheapauto.com.au/4wd-recovery/uhf-cb-vhf-ra...
(the same can't be said of cassette recorders or answering machines or VHS camcorders)
[2] there were many attempts to make smartphone apps where you can communicate with people that are physically around you. These never picked up steam and the two examples I remember are now defunct (I can't remember the names, I will update this post if I find them)
EDIT: the apps in question were called Highlight app and Glancee app.
Highlight:

Glancee still has a website, but it no longer exists as a standalone app as they were acquired by Facebook many years ago:
