The trick to get around this is to move smoothly up and down the gradient of social interaction intensity, never dropping below a basic floor of presence: the sense that there are other people in the same place as you.
Instead of having two modes, “in a call” and “on my own,” we need to think about multiple ways of being together which, minimally, could be:
In a video call
In an anteroom to a video call, hearing the sound of others
In a doc together
On my desktop but with the sense that colleagues are around
And the job of the designer is to ensure that their software ensures the existence of these different contexts, instead of having the binary on-a-call/not-on-a-call, and to design the transitions between them.
But the coppersmiths themselves, in their desire to do better or otherwise than their predecessors, soon quit the line of truth and propriety. There comes then a second coppersmith, who proposes to modify the form of the primitive vase in order to seduce the purchaser with the attraction of novelty...and it becomes fashionable, and everybody in town must have one of the vases made by the second coppersmith. A third, seeing the success of this expedient, goes still further, and makes a third vase, with rounder outlines, for anybody who will buy it. Having quite lost sight of the principle, he becomes capricious and fanciful...yet everyone applauds the new vase, and the third coppersmith is regarded as having singularly perfected his art, while in fact he has only robbed the original work of all its style, and produced an object which is really ugly and comparatively inconvenient.
