I had the opposite experience. I started my professional life during the early days of the "open" floor plans. My first work desk was basically in a hallway without even shitty fabric cubicle walls to block me from my neighbors. About 10 feet away from me was the row of sales people, on conference/sales calls all day.
When I first started working remotely, it was a miracle. I finally remembered what it felt like to focus again. I hadn't been able to think so clearly and deeply since college. I had previously thought my mind was suffering early dementia, but it turns out it was just that standard office environment does that to me.
I will say I did miss some of the socialization. I had to consciously step up my outside-of-work socializing time. I think all but the most social people could do this if they made a conscious effort to maintain their social/mental health while working from home. Having young children at home also makes this difficult without a dedicated office and stay-at-home-watching-the-kids-full-time spouse. The big problem right now is people are not capable of compensating for the lack of in-work socializing with out-of-work socializing. I imagine that's extremely difficult for most people.
