Chat is only the latest incarnation of human communication.
The problem, now, is that basic communication is too complicated and time consuming. Today, even with fancy smartphones and LTE networks, exchanging bits of text is getting more difficult instead of easier! There are too many different chat apps. I can’t search across all of them. I can’t even remember which of my friends are on each app. It’s become even worse than the rats nest of cables we had to deal with before USB.
This is meant to be human communication. Technology needs to fade into the background, so I can simply chat with my friends, family and work colleagues. We need a universal communications bus.
