Cities exist on a sliding scale of digitisation. Anything in a city that is not digital is considered analogue. Many of the core functions of cities are the definition of analogue, e.g. roads, bridges, water systems, buildings, parks, hospitals, and airports.
Smart City development is not linear and developing countries should advance in leaps and bounds. India is having success.
