Those two experiences can live in parallel. I used to have 2 or 3 days WFH to get shit done, and 2 or 3 days at the office to see people. I do my own time-tracking, so I can even quantify the degree to which my office days are less productive, yet I still choose to go there. Not to concentrate, but to grease the wheels of projects and work relations by being there in-person.
I think it's detrimental to a team to go all-remote when the grey area of sometimes-remote contains the best of both worlds.
