Earlier quoted context omitted.
Ah come on, this is not accurate at all. We have tons of tech now: audio, video, charting, etc. Circles are pretty easy in powerpoint or any such software. The tech is obviously here already. But still, why do people prefer sending chat texts instead of calling or video calling? Surely not because of tech.
In my case because of the asynchronous nature of text versus vide or voice calls. An effective compromise is voice notes in modern messenger systems, which preserves asynchrony while also allowing the expressiveness of speech.
- you send me a picture, it may be ambiguous;
- you leave me a voice call, I have to go out of the meeting room to listen to it
- you write a message, it just works. If there is info to use, I will easily copy your message in any application (Excel, Word, SAP...).
Also, text can be stored easily, so I will keep an archive of your text, probably far less an archive of your voice message or diagram, as they are very heavy.
