the $5 bn. office building will make the 12,000 employees there more productive. But its being done 3X as costly per square foot as typical skyscraper (instead its a ring like the Pentagon sort of, but much more land, very expensive Silicon Valley Land alone $1 bn. with improvements and tunnels..etc.). Don't blame this on Cook..... it was Steve Jobs IDEA a "mausaleum" to himself in effect.
