I suspect the author is pro-mob programming and pro-open office spaces. ;-)
Similarly, I think open office spaces provide opportunities for group bonding and collective thought that simply aren't available when everyone silos in corners with doors closed and blinders on. But I also recognize the need for quiet time and uninterrupted spurts.
What I am against is a dogmatic adherence to "one right way" and the special status afforded to those who demand it, something I have seen with regularity in the tech sector.
