Is it possible to travel every city in the world?

Theoretically, it is possible to travel to every city in the world, but it would be an incredibly challenging and time-consuming endeavor. There are over 40,000 cities in the world, and visiting each one would require extensive planning and resources. Factors such as budget, visa requirements, language barriers, and health considerations would need to be taken into account. Additionally, some cities may be in remote or dangerous locations, making travel to them difficult or even impossible.

Despite these challenges, there are individuals known as "city nomads" or "world travelers" who have made it their goal to visit every city in the world. Some notable examples include Alberto Cairo, a data journalist who has visited over 1,000 cities, and Doug Lansky, a travel blogger who has visited over 180 countries. While it may not be feasible for everyone, the idea of traveling to every city in the world is a testament to the human desire for exploration and cultural discovery.
