I used to be a mobile app developer but I literally retired because my company went to an open floor plan arrangement with no offices at all (let alone doors for them) or even cubicles. You didn't even have your own desk, you just sat at any empty desk when you came in in the morning. The uselessness of the back-to-the-office movement is obvious enough when compared to working from home, but it's really even worse than useless when you can't get a quiet, undisturbed environment to do your work in.
