Funny, the quoted Architecture Firm in the article is Gensler, who designed my last company's office space. Which included 6 rows of desks[1], each row seating 8 people with no separation left and right, and only a low divider between the person in front of you. And they designed it in 2015, 3 years after the PDF the quote was taken from was published. Sounds like even they aren't buying into the "open offices are dead" narrative.
