I doubt it. Although I think a quiet private office is the best environment for those times when you need hours of uninterrupted concentration, other changes make open offices tolerable. My 4k screen occupies almost all of my field of view. I like ambient music for the coding trance. Instead I predict the death of the office. Remote work in dispersed co-working spaces is even more cost-efficient than an open office.
While home offices are more cost- and time-efficient (no commute, no office cost to employers), I still come into the office despite having a decent set up at home. I'm more productive here even with the open plan, the time lost commuting, etc. And we have had steady enquiries from prospective tenants, all in a similar situation.
Going by HN, not everyone loves open plan, but for me, the advantages of a shared, open office are: people being able to see my screen from afar mean I'm more likely to stay on task rather than get distracted and research holidays non-stop, I enjoy the social interactions with colleagues, and face-to-face is best for collaborating.
I think we'll see dispersed co-working spaces for a while, at least until VR is strong enough to emulate the benefits of working with peers.
