I think it's also possible that things will drift to both ends of the spectrum.

Something like 3-in/2-out feels like one of those uncomfortable middle grounds. OK. So workers get a bit more flexibility. But the downsides:

- Companies can't really save on real estate unless you do scheduling and hot desking which seems like an ugly solution.

- Workers can't really increase their commute times much but have to keep a reasonable working area at home.

- Schedules will only overlap for meetings etc. if there's a lot of coordination

- Either remote people on a given day will get left out or some of those in-person will resent having to work as if everyone is remote even though they're in-person themselves.
