I have my wills, of course, some are doable, some are not. I really want to be immortal, never fell ill, find a large plethora of sex-hungry partners and so on, these are just few examples of not really doable personal will. If the office can economically survive because it does work it will, if the slice of those who want WFH is big enough to kill the office that's how democracy works. I do like WFH, I do not pretend imposing others the same, as long as others do not pretend imposing me the office.
Of course I observe issues and strong points in both models, so the future will be decided by the majority anyway. We will see, knowing that any imposition tend to last less and less as more and more it's imposing and impacting people life.
