Those buildings are hardly full of developers. Most of them are accountants and boatfuls of bullshit jobs. I know because I work among them.

Look at Canary Wharf at lunchtime and tell me with a straight face that those are developers.

Of course no building is full of a single thing. The one I worked in had full floors full of developers, that adds up to quite a decent amount.

Ironically, accountants and finance folks eat at their desks, so if you see people outside at lunch time, they might very well be technology folks. They'd be wearing shirts though, easily confused with business people.
