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.
I recognize this is a very niche endeavor, but the art and craft of maintaining a homepage, with some of your writing and a page that's about you and whatever else over time, of course always includes addition and deletion, just like a garden — you're snipping the dead blooms. I do this a lot. I'll see something really old on my site, and I go, “you know what, I don't like this anymore,” and I will delete it.
But that's care. Both adding things and deleting things. Basically the sense of looking at something and saying, “is this good? Is this right? Can I make it better? What does this need right now?” Those are all expressions of care. And I think both the relentless abandonment of stuff that doesn't have a billion users by tech companies, and the relentless accretion of garbage on the blockchain, I think they're both kind of the antithesis, honestly, of care.
