Open plans are much better than cubicles. The transition to open plans and standing desks has been a boon for social interaction in teams, more role-crossover, and just more physical movement in general.
Office Space is a timeless and incredible film, but one aspect of it that seems almost like fantasy is the idea that people primarily working on software might sit down in cramped cubicles and prefer fake privacy to real social interaction.
edit: Look, I know that some people like cubicles. If you do, that's fine. But if you actually seriously like small, cramped, stuffed cubicles in Office Space (or The Matrix) - which absolutely existed in the late 90s and early 2000s in IT and seem to have largely disappeared - I'd really like to hear why. If you do like cubicles: how do you move? Do you really have the discipline to get up and walk around every once in a while? Or do you end up having much less body movement than open plan participants?
