Earlier quoted context omitted.
While I also find long 1-1 meetings tiring, the camera does nothing to improve this for me regardless of who has it on. What about seeing a face makes it less tiring than not seeing a face? Is this possibly an introvert vs extrovert thing?
Well, the problem for me specifically is the "hurry up and wait" feeling. If the person operating a computer is doing stuff related to the meeting, time seem normal for them. But the person waiting has to remain focused to answer follow-up questions, so multitasking might not be a possibility. Seeing a face helps in my experience, but I have no idea why. However, screen sharing is probably better. Or just not having…
My 1-1's are almost always to discuss or troubleshooting something, so not much "downtime" at all. When troubleshooting, screen sharing is almost always used, otherwise I probably don't need the other person at all.
