I disagree fully with that statement. It’s completely oversimplifying the reasons to mostly work from home. One might want to spend more time with their loved ones, save money because of commute, might enjoy knowledge seeking and learning by themselves and love long focused work. You can get the human experience in many different ways. For example why meeting the colleagues at the far away office if most of them leave near downtown? You can have retreats and goal oriented team events… there are lots of possible combinations.
