On the long, weary stumble from the airplane door to immigration in Bangalore’s Kempegowda airport, the moving walkway takes you past a large room behind plate glass windows, where about 50 serious-looking men and women sit in ergonomic chairs behind multiple monitors, engrossed in some sort of important airport business. Putting them on display is very smart. You immediately get a sense of competence, order and safety, and a visual reminder that Bangalore is a world tech capital.
