I totally see the value of cultivating ideas in a private space without constant background noise, and then sharing these ideas with the right arguments for feedback when you see them as ripe.
Unfortunately, the narrative by big tech has popularized the notion that these open spaces with everyone speaking over each other has great productivity and collaboration benefits. It saves them a lot of cost to not build and maintain humane cubes, but other arguments of how great it is for "me" are just bogus.
