>The problem is that people under the age of 40 or so don't communicate via phone calls in the first instance.
Where on Earth are you getting this information? You've made an unsupported claim that I was able to debunk by talking to the four tables around me. What's your source for "people under the age of 40 or so don't communicate via phone calls?"
I literally don't think I've been called unannounced by someone under 40 in a decade. In fact I think it's now something of a social faux pas to call unannounced. Maybe the people around your tables are just really rude?
The first one says 'millennial[s] won't take your phone call' in the first line. Then it even quantifies it 'a quarter never use [their phone] for calls'.
If a quarter of people you might be meeting never make or take a phone call, how successful do you think you're going to be in trying to reach them via a phone call?
'Most of the twenty- and thirty somethings I socialise with would rather suck Donald Trump’s toe than make or receive a call in order to have a chat'
