This is in 30+ years of working.
Open space office with more than 50 people on each floor, it was very interesting for a while(as you can see how $2B business is run in one picture) but it was one of the primary reasons I quit.
Beyond the ongoing noice and distractions, it doesn't allow you to have cycles of work and thought. Well, I actually would have them but it feels weird to be the guy who stares at random things and people for prolonged time :)
This is at one of the majors.
Apple is usually a smart company, but it is always a large company, and large companies are prone to making broad one-size-fits-all mistakes.
And another one. Then a third.
And then when you start facing the prospect of your employees getting lynched by locals who are furious about their rent, ask some other cities if they might have room.
My prediction for the future: Amazon's internal transfer process is extremely smooth. Seattle is not gonna weather the opening of this second HQ well, once it gets up and running. But the point is, you gotta keep moving forwards - it's always day 1, right?
How do companies believe in ever-lasting growth and then not reflect that in their plans on usage of space? Feels like cognitive dissonance to me.
On the micro level changing from offices to open floor is a huge change. How was that supposed to preserve and foster the engineering culture? Apple is the company where walls and secrets are not accident but carefully designed. I could imagine a part of the organization going to open floor but the whole building?
