Companies will be competing with an increasing number of "remote first" or "ultra flexible" workplaces. These companies may think they want plexiglass dividers now. But new candidates will have offers between "work from wherever" or a plexiglass labyrinth that looks like a modern supermarket checkout on steroids. Why would a candidate choose the plexiglass open office? If the company had a flexible arrangement between the plexiglass jungle or a chill WFH environment, who would work in the open office? As companies realize that many don't want to live in their city, and many others don't want to go to their office, they're going to have to compete to make their office more enticing if they want a world where people still go to an office.

Of course, this depends on the broad WFH trend coming closer to gaining critical mass.
