Software and knowledge jobs take very little space - just whatever a single employee takes up. Even in a small private office setup not much, but even less in open plans - here's perhaps a hit to why open plans are popular in offices that are predominantly on expensive land. There is very little space required for storage and for moving large objects around, no loading bays etc. A 10,000 employee software "plant" take up a lot less space than a 10,000 employee manufacturing plant. It's exactly because these industries are high-productivity (per land unit) that they are practical on high value land.
