I am in the lucky situation having worked more years in offices than open floor, last time 2018. The doors were only shut before 1995, never after that. I was typically the only one who turned his desk towards the door, so I could chat with people coming in and also show that people can come in. It was so much more productive to work as a developer compared to open space.

Nowadays I go to the office (open space) only during evening hours when at most 2 hackers are there. Working from home probably not productive when you have smaller kids. Maybe good for the kids though.
