Over the past decade smart urban technologies have begun to blanket our cities, forming the backbone of a large intelligent infrastructure. Along with this development, dissemination of the sustainability ideology has had a significant imprint on the planning and development of our cities (Yigitcanlar 2016). Consequently, the concept of smart cities, evolved from intelligent cities (see Komninos 2008), has become a popular topic particularly for scholars, urban planners, urban administrations, urban development and real-estate companies, and corporate technology firms. There are numerous perspectives on what a smart city is. These are ranging from purely ecological (Lim and Liu 2010) to technological (Townsend 2013), and from economic (Kourtit et al. 2012) to organisational (Hollands 2015) and societal (Deakin and Al Waer 2011; 2012) views. Moreover, as for Kitchin (2015), smart city symbolises a new kind of technology-led urban utopia. Utopia or not, in all these perspectives the vision of technology and innovation is a common ground to shape our cities into a form that we want to leave to our descendants. In this paper, the smart cities concept is viewed as a vision, manifesto or provocation—encompassing all techno-economic, technosocietal, techno-spatial, and techno-organisational domains—aiming to constitute the ideal 21st century city form. Presently, there is no fully-fledge smart cities exist. Stated by Glasmeier and Christopherson (2015, p. 4), “[t]he global smart city market will be valued at $1.6 trillion in 2020. Over 26 global cities are expected to be smart cities in 2025, with more than 50 % of these smart cities from Europe and North America”. At the moment with the building of these cities underway in a number of places around the world, smart city examples abound in both the popular media and in academic discussions. This provides us the ability to systematically re-evaluate the definition of smart cities.
