I think age plays also a role. I have met various young people who have't entered the "working world" yet, that only have an email address because they needed one for registration and to recieve some school related information. But it is percieved as something completely arcaic and they never use it for anything else nor check it regularly. All communication is via messangers or social media.

On the other hand also elderly are or could be moving in this directions. E.g. my mother getting an iPad and apps like Whatsapp have completly changed "computers" for her. From, being mostly a chore that you have to use, to something really useful for getting information and to stay in touch with relatives in other countries
