"Organic" neighborhood? Let's be realistic. Most of the major developments around Boston--present and future--are on old industrial sites and rail yards: NorthPoint, Assembly, Allston, Boston Landing, Seaport, Chelsea, Everett.
Only two that I can think of, Kendall and Fenway, had people living alongside industry--and so have a history of livable neighborhoods. I'd reserve criticism for the "natural feel" for a place to those two areas. Otherwise, you're starting from scratch.
Boston has its historic, slow-build neighborhoods, but these aren't them. As an aside, neither the Back Bay nor the South End could be considered organic in their growth. Back Bay was largely designed by one firm:

Charles Bulfinch is to thank for the South End:

And before you say, "This ain't the Back Bay," let's consider the cost of building now versus the 1860s, pre-regulation, unionization, and litigation. Brownstones come cheap when built without a minimum wage law.
