After the deluge of spam calls I receive daily I'm somewhat inclined to opt for the opposite direction. No more phonecalls and just using apps for communication.

At this point I would like to be there. Telecom companies don't seem to care about spam calls much.

That's so much better. I only communicate with people who have the rich man's apps. No unintended negative side-effects can possibly be found there!

Phone has become much more than a caller. It's become a cybernetic extension of our self, and are even used to validate our identity.
