Yup. For work that can be done remotely, I think there are only two stable points. One is where you and your colleagues are in the same space almost all your working time. The other is full remote probably with occasional get-togethers for bonding and close collaboration. (Monthly to quarterly are the common frequencies I see.)

I suspect anything in between won't work very well. "Come in when you like" is obviously untenable; if there's no knowing when your colleagues will be in the office, then there's not much point in going in either. (Except maybe to near-to-home cafes and coworking spaces, which I expect to become more popular.) All of the N-days-a-week compromises end up seeming pretty arbitrary.

I honestly really enjoy close, collocated collaboration. But it seems so impractical to get all the right people close enough that the productivity bump is worth the commute. I expect I'll be working mostly remote from now on.
