There are so many different ways to communicate currently, that soon we aren't going to be sure what app to best contact a particular person with. You've got Email, SMS, iMessage, Facebook (Chat), WhatsApp, Twitter, and those are just are some of the top ways.
Everyone has their favourites and because of this, communication is getting more annoying and difficult purely because of the diversity of choice. Its not helped by large companies vendor locking their customers into a specific way of messaging, fully knowing that not all of the people they contact are there.
I have a strong opinion on this yet I have no real solution.
Whats the chances of the top tech companies coming together to create and implement a secure open protocol and/or app allowing end users to message anyone regardless of platform? I guess its pretty bonkers.
