It's a technology that you need to be rather firm in to use it. There are many tools, but often they are a little "hacky" to non programmers. That's why it gets more and more replaced by the FB chats, Whatsapps, Skypes, and Snapchats of this world. The same goes for email. Email will die a slow death. Maybe even your children can still build a career out of email know-how. But it's more and more replaced by other technologies. Just look at China were people all didn't know the internet in its youth. The first contact to internet most of the Mainland Chinese had was with mobile solutions like QQ (their ICQ copycat). For them email is like a harder way to do the same thing that you could do just as well with Wechat/QQ. So even the most serious of corps in China have Wechat/QQ support and phone, but they might not even have an email support. This will come to us, too. Just slower because people know email already.
