This looks like a natural reaction to remote work. My anecdotal observation is that companies are giving up the ghost of offices, but employees are hesitant to commit to a full-time remote world for fear that their employer will pull them back one day. Even if the employer decides not to pull them back, there is no guarantee that they will find the next in a remote world.

But, in the middle of the day - I still see empty offices all across town. At some point something is going to give.
