> Before we had open concept hellscapes, and the cubicle farm, people had actual offices

It is true, but the move to cubicles and in the end open halls was necessary because rent in prime employment centers of the world has gotten so high, and companies seem to be requiring ever more people and we cant afford to give everyone an office nowadays. Modern office is definitely better in some ways socially, I dont think you will be really motivated to go to work if all you had was one room to sit and close the doors to not see anyone. These days, You have more people to talk to if you want and sometimes its a good and safe environment to discuss things. If I had to sit in an empty room to work and then it wouldn't be any different than working from home.
