Open Office was a cesspool of disease, even before covid it was problematic:

Studies have found that that those who work in open offices are more likely to take short term sick leave or a sick day. Those employees might be using 62% more of their sick days due to the environment. Employees with this office layout are also more prone to headaches and respiratory problems due to weakened immune systems.

Through the course of my career I've somehow lost office space as I've ascended the corporate food chain. I had a private office/technician room in my first job out, then had an eight foot cubicle with high walls, then a six foot cubicle with low dividers, and then the pandemic hit. The operations guy at the last place was making noises about a benching arrangement after RTO, like people were going to put up with being elbow to elbow with Chris The Conference Call Yeller and Brenda The Lip Smacking Snacker while Team Loudly Debates Marvel Movie Trivia is yammering away the next row over.

Hell, if it meant getting a space to myself with enough privacy to hear my own thoughts I might consider giving up my current WFH gig. But everybody's obsessed with building awful office hellscapes and I don't have the constitution to put up with that kind of environment.
