Agreed. Although I did miss meeting engineers from other disciplines (EE, Mechanical, Chem. E., etc). I'm not sure if they are simply scarce in Manhattan, or if I was in the wrong places.
I did, and they were fine. Still no aerospace engineers or plasma physicists (for example).
I'm assuming that a greater portion of that type of work isn't do-able in an office farm. Businesses need to make a certain amount of money per square foot, so labs and whatnot aren't feasible.
