We'd be better off with only text communication allowed between unknown parties. It's much easier for us, as humans, to quickly parse text and it's far less disruptive to our lives. I'd like it if calls only occurred between parties who already agreed to that form of communication.
As someone living in a country that uses my third language, texts - where I can use translation tools, or just take my time to read something slowly - are a million times easier than spoken conversation.
Everyone else, leave a fucking note.
