You may be surprised to hear this: that part about "stay in one place, do not talk to each other and look straight down" is true even in Japan and Korea, even in many high tech office settings. My vivid recollection when I worked in Japan was "These people are so nice outside the office, why do they become such expressionless robots inside?" I have many close friends in Japan (and we have done a lot of fun stuff outside the office), and so I would ask them this. They would shrug and say "At work we have to wear a mask, that is just the culture here, everyone has to conform to it." It felt oppressive to me, but they seem to take it in their stride.
