**3. Conclusions**

Smart city development builds bridges of enablement for all of its citizens, matches their overall and individual demands, and enables assistive technologies and key communication among the citizens, the city, and government that responsively resonates and patterns the future city. Learning smart cities increasingly makes use of assistive technologies in the widest sense and narrow sense to enable all of their citizens. Catalysts of smart city development are needed whenever the free market does not provide a satisfactory solution on time to catalyze various aids or to reach higher stages. Assistive technologies will drive innovation in the field of robotics, artificial intelligence, digitalization, transportation, and also cyborg technologies and advances in many other fields like smartphone technologies.

Maslow's pyramid of citizens needs will stay the main orientation for smart cities and all citizens including the needs disabled, aged, young, unemployed, troubled, or poor persons. New ICT and web technologies can assure a faster and more informed progress toward more functioning, comprehensive, assistive, healthy and nice city patterns, better reciprocal communication and more autonomy and independence of all, and the collective of citizens. If done right and if the new level of personal information is not misused against citizens, such assistive ICT technologies [7] could boost smart city evolution by better coordinating and integrating all of the efforts and by finding a smarter way in which supply fully matches demand and assuring everyone gets the assistive technology help needed. By improving our help for people with disability, cities and countries can also learn how to improve the lives of all citizens by finding the right bridges of enablement and assistive technologies for everyone everywhere and by assuring sustainable career paths and good city lives for all. An "ongoing" but not trivial future work and important case study is the advancement of what is called "e-governance" [12, 18] by the new IT and ICT fields of "e-inclusion" [19]. Assistive technologies are high-tech drivers for many new innovations that create jobs, and smart cities and assistive technologies can best grow in a socially sustainable environment with a good communication and understanding of all decisive circumstances—so we should incentivize more efforts on common grounds to unleash our smart potentials and dreams.
