They don't necessarily need to be big offices. It's just that corporations generally do seating based on seniority and status, not need. They have tiny cubes for worker bees and giant private offices for the queens.
Even small offices require more costly building materials than large cubicles. So even a high density might still be somewhat expensive. Fortunately, there are opportunities for cheaper commercial real estate these days, so someone has the opportunity to try something new.
Cube farms aren't really much better for programming work than true open-plan offices.
The article is about the split between "office with door" and "not that", not specifically open-plan offices, so talking about cube farms is absolutely valid.
What on earth are you talking about. No one is debating true offices are superior but a full height cube is about infinitely better than open office. Cubes are sound insulating, they're quiet, they're more spacious than open office. You have storage and three to three and a half walls. The only physical distraction is caused by people walking past the opening. It's not just possible, but quite likely to eliminate outside movement from your field of view.
I'll admit that plenty of cube farms are really just open offices in lipstick but true cube farms are far superior to open offices.
I worked for a few years in the full-height kind, and a few years in the lipstick kind. The full-height cube was awesome, I had as much privacy as I really needed but the barrier to interruption was just low enough that people weren’t afraid to come ask a question.
I think cube farms are substantially better than open office plans. I simply cannot function in an open office layout, but I can in a cube farm, albeit at the cost of productivity and the level of thinking I can accomplish.
Open plans have visual and auditory distractions. Cubicles with decent walls at least eliminate the visual distractions. On the other hand, glass-walled offices might have decent soundproofing but have the distraction of people constantly walking by.
There's also the question of form vs. function. A lot of people in leadership care a great deal about the workspace looking "modern" and care less about it being effective for the people working in it.
Even small offices require more costly building materials than large cubicles. So even a high density might still be somewhat expensive. Fortunately, there are opportunities for cheaper commercial real estate these days, so someone has the opportunity to try something new.
