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.
Should we really demand that the guy who checks ticket stubs at the movie theater hones his craft?
Well, yes. No job is too low to not warrant care, because no job exists in isolation. Carelessness ripples. It adds friction to the working of the world. To phone it in or run out the clock, regardless of how alone and impotent you might feel in your work, is to commit an especially tragic—for being so preventable—brand of public sin.
Bob [the driving instructor] oozes concern; he wants to infect the state of New Jersey with good driving habits. He respects his public role, the fact that the minute he's done with these kids they head straight for their parents' car keys and out onto the roads we share. When I asked him what he likes to do outside of work, he laughed: "This is my life."
