This type of development and land use is increasingly being abandoned because it's sterile and unsustainable. Portland, Greenwich Village, and Boston provide some great examples of how more integrated "metropolitan" settings can develop as beautiful and vibrant engines of broader economic and social development--the likes of which you will not see in a private walled garden.
How out of touch are you? This is CUPERTINO we are talking about. With NONE of the civic urban infrastructure available to support the ecosystems of those places. Daly City and north, you might be able to start having that conversation as a realistic thing to consider. South San Francisco and below, it's just completely not relevant. Don't they teach architects how to assess a particular site as well as working with the site and surrounding environment anymore?
The design of the new Apple campus is striking, and a big improvement over what's there now. But Hawthorne's critique is valid; the design is retrograde--its futuristic only in a mid-20th-Century kind of way. Designed as an isolated island, rather a 12,000-person part of Cupertino, the design might be a good one for Apple and very much in it's image, but it's not a great design overall. It's very much like failed mid-century attempts at urban renewal, and Le Corbusier's discredited modernist visions of freeway connected skyscrapers in park-like settings--just with the building laid on it's side.
Urban renewal failed to take the realities and capabilities of their sites into proper context, forcing something the community wasn't into the community. Even worse it was forced economic relocation and upheval. Here the example you tried to use fails for the same meta-reasons you are proposing as flaws in the Apple design-- that Apple's design is disconnected, because there isn't upheaval, relocation of infrastructure and community it must be a flawed design, hurting or at least depriving the people of the world. It sounds like a harsh comparison and it is but it's fair. You can't get a Greenwich Village, hipster Portland or Boston feeling neighborhood without catastrophically changing what Cupertino is. That would be just as tragic to try to force as urban renewal was.
It's a private office complex, not a shared public space. How hard is that to remember? It replaces haphazard nondescript but very visible boxes with trees and a big interestingly shaped building actually sited to not overpower the neighbors. It is being engineered to use significantly less grid-electricity than a standard comparable service buildings serving the number of employees planned. It is the kind of infill that should be embraced wholeheartedly and used as an example of what can be done with ugly office parks in the future, rather than lament it isn't Greenwich Village, hipster Portland or South End Boston, forgetting what the rest of Cupertino actually is.
