Earlier quoted context omitted.
an unsupported assertion is not conclusive proof. we’ve seen that people have been trying to substitute in-person meetings with video calls, but that doesn’t prove any additional utility beyond a conference call. even in educational or therapy/coaching situations, a recorded instructional video accompanied by a phone checkin likely has better outcomes than video chats.
You miss my point, I think. Everyone who has access to video calls could trivially turn them into conference calls instead. The fact that they continue to prefer video for at least some situation demonstrates that, regardless of what else is going on, they find the video calls to have some additional utility. If your hypothesis were true, we would not observer this behavior.
in any case, your argument is circular because you're implicitly asserting utility must exist ('if they use video, it must have utility'), and then pointing to that just-asserted utility as (unsupported) refutation.
