You are years behind. It was in 2016 that, when traveling and wanting to exchange contacts with cool local people I met, I first began to get the response “My e-mail address? I don’t have email.” Already then many younger people were only on social media, and it was expected that you would exchange those contacts. And some countries never had the email moment at all, so even older people don’t use it.

Ditto for phones, if you mean the PSTN – as time goes on, fewer and fewer people have ever really used that. When people around the world are communicating via their smartphones with a phone-number-based protocol, it’s overwhelmingly WhatsApp, and guess who owns that?
