> That’s one of the issues I have with open floor plan offices: people buzzing around in my peripheral vision can be incredibly distracting and detrimental to productivity depending on the day and my mental state, and there’s almost nothing that can be done to mitigate that.

Don't worry, the office-lords have solved that! You can book a focus room for no more than 60 minutes when you need to focus. PROBLEM SOLVED!!!! /s

People who complained about cubicles were probably mourning the loss of an enclosed office (which I imagine is far superior). As we are learning, it can always get worse, and what was once bad is now good by comparison to what we're getting now.
