>This takes extraordinary discipline on the part of the in-office team. Fortunately, everything that's good for a remote-first culture is also just good for communication in general.

I think it's even harder for companies that have open open offices or are doing Agile. Those two things usually mean the companies are explicitly stressing in-person collaboration. In-person communication isn't a bad thing by itself, but I think that explicitly valuing in-person communication ends up making remote work harder.
