It's one of my favorite books; throughout my time reading it I would periodically put it down and just sit with awe in imagining the science and the work happening there throughout the years depicted.
I need to sit down and read it again; but I'm afraid to, as in a way it just gives me this odd sense of mixed unfounded nostalgia and jealousy and a bit of dread for not being a part of something similar anymore.
In some corridor, somewhere in the world, the next Bell Labs is currently under way and others will read books about it in the future. You just have to figure out where it is :)
