There's lots of communication which is hard to do remote. The water cooler is o e thing. But even in a meeting when presenting something the feedback is limited. When sitting in a room it's simpler to see whether people are following and one should go faster or iterate on a point. Also one can simpler intercept with a question or comment. The text based back channel is limited for that.

(I WFH exclusively for 10+ years and still regularly miss the office for anything which isn't deep down coding, but requires communication)
