But I literally can email somebody from email-provider a to email-provider b. But, lets be realistic, if the email would be discovered/invented today, that would not be the case ;-)

This is true; every non-ephemeral messaging system on social networks is a replacement for email. A poor replacement.

If they are a poor replacement, why does anyone use them?

[dleslie]

A better question is why does anyone still use email if these alternatives are superior.
