Having worked on a number of early stage startups and projects, in varied remote/in-person settings, and currently fully remote, the only thing I genuinely miss from an office is having a huge whiteboard to gather around. In my experience, whatever gains come from increased communications bandwidth in-person are kind of a wash with losses to focused work being in a distracting environment.
