I dunno man, I (software engineer for 21 years) like the open office, at my last job we had real offices and my coworker and I cut a huge window sized hole in the drywall between our offices so we could easier communicate/chat. I can’t count how many times a random casual conversation saved the day or generated new ideas. If I need to focus I put on headphones.

Logistically it seems unlikely open offices will go away, software heavy business can’t just spread their workforce over 3x the space, especially in dense urban areas. Better to come up with novel solutions for deep work, like dedicated open area library/dark dungeon rooms.
