>Nope. A properly-designed office is a space specifically and professionally arranged for one thing: to increase the productivity of work.
That has never been the case in my experience. You want an office space that increases productivity? Individual offices for everyone. With a proper door and walls that gives privacy for everyone.
When we had cubicles it was decided too much space was being wasted. Lets go to open office and high density seating. Cram more people into the same space. No walls between people. So your constantly looking into someones face, their movements distracting you. When they are on the phone you hear it. If they have a conversation at their desk you hear it. That lowered my productivity. Noise cancelling headphones helped but didn't completely solve that problem.
Being able to walk up to my desk and interrupt whenever they want lowered my productivity. Sending an email or a message is better. Find a good stopping point then changing focus rather than just ripping you out of your focus randomly.
Those that want to go to the office should feel free to go. No one is stopping them. But so far I haven't heard a strong argument why WFH, that we have been doing for the last 3 years, is less productive than when we were in the Office.
IMO this boils down to highly social people vs not very social people. And developers tend to be not very social people. People managers tend to be highly social people. Will be interesting to see how it plays out in the end. But in tech at least the highly social are the vast minority.
