I suspect it will die a very slow death. Home working is increasing as internet speeds finally are starting to get up to a level where serious work can be done., but many companies will need people based in the office for a very long time.
Also many need to get 'out and about'. I was taking careful note of my SIL (a fiscal adviser) on a recent visit. He is never far from work but clearly needs to work with others, so has time at home, time in the city, and time abroad with clients. Alright, back office staff are not needing that pattern, although people do work in teams, nevertheless. Synergy appears to need physical proximity and I don't see that changing; indeed there seems to be more need for successful firms, whether it's engineering, financial, or any other discipline. I cannot envisage artistic and design teams working apart. It's similar with client contact of course (perhaps most important of all).
