Over the last few decades? So you've been around long enough to remember prior to 5 years ago, when video calls were not the norm, and voice-only conference calls were. We all got by just fine that way, for a long time.

I'd say that yes - video gives more info and context. But that additional info is not required for effective communication. And it can really lag people with slower internet connections, which makes it more difficult for the conversations to go smoothly. I'd rather have a lag-free voice conversation any day.
