Exactly zero people I regularly communicate with other than my teenage son uses any of those regularly.
The only people who use RCS to contact me are businesses sending notifications or spam.
Unlike e-mail where I do get personal correspondence regularly.
I don't expect my experience is typical, but I don't think yours are either - we all live in bubbles.
I suppose you could say being younger is living in a bubble. I assure you nobody under 35 is using email for the majority of their personal correspondance. Email is for business.
The claim above that we responded to was much broader.
