Not to laugh too much, because I agree with you, but...
You do realize that what you're positing (giant work buildings, close together, with all needed facilities nearby and lots of intra- and extra- transit access to nearby housing) is what most of us call an "urban downtown area", right?
You don't need to invent this. People already figured it out.
Y, I do! That companies seeking an isolated, concentrated workforce somehow vibes with new urbanism is a big stretch. Worse, I am biased by the aesthetic and technical qualities of this building concept, and it overwhelms practical considerations. This is exactly how so many planners bought into modernist architecture.
