Earlier quoted context omitted.
IDK, to me text has higher information density and throughput than a video meeting. Ever listened to a swagger file?
That really depends on the meeting and the nature of the information being shared. If you’re communicating purely technical information about a subject everyone is already aligned on, text is fine. But the information density present in facial expressions, vocal inflection, body language, etc. is significant and much is lost without it.
You are right, though. If all your meetings are about persuasion, video and audio will be best.
If someone is in a technical role and most of their meetings are like this, that's a bad sign.
