Living in a smart city has numerous benefits, aside from increased efficiency and reduced energy consumption. For instance, smart cities often feature advanced transportation systems, such as self-driving cars and smart traffic management, which reduce congestion and emissions. Moreover, smart cities provide their residents with access to a wide range of community services and public amenities, including digital libraries, online healthcare platforms, and smart waste management systems. However, there are also some drawbacks to consider. The high cost of living in a smart city can be a significant burden for low-income residents, and the reliance on technology can make the city vulnerable to cyber-attacks and technical failures. Furthermore, the collection and analysis of personal data by smart city systems can raise concerns about privacy and surveillance.
