Not sure where you got the idea that I think that new office buildings are dead (unless I misread your post). If anything, my post supports your take in a sense that it it advocates for construction of new office buildings around Penn Station and conversion of old ones into residences.

Having said that, the area can definitely use new residential construction, as well. Ita not like living within a direct train ride of anywhere in Manhattan and literally all of the metropolitan region is not a highly desirable amenity.
