This will probably happen as the sunk cost fallacy of existing office space goes away. They have these big office spaces leased out and they're contractually stuck with that cost. Those leases will expire over the next few years, and a lot of them will decide they don't need them anymore. Until then, they're paying for something that isn't getting use, and there's mental pressure to force the issue.

This will coincide with a collapse of the office rental market. The places heavily invested in that market see it coming, are dreading it, and are driving headlines saying how much better office work is.
