Over the last couple of years, no one in any of my team calls has ever turned on their video feed. Primarily because they don't want to get "ready" for each call. So it's a video conference only for screen sharing purposes. All other video feeds are off. The web cam quality without exceptional Youtube studio level lighting is crap anyway. And how unportable is a dual monitor setup?
In the future where multiple participants have a headset, there can be multiple screens shared at the same time. Multiple users can be visible and in that case, it's just better to have digital personas because no one will want to turn on their video feed otherwise. This is the future of web conference. This is the future of remote work. The sooner you see it the better for you.
