During the last century, contact between different parts of the world has developed considerably due to the prevalence of air travel and telecommunication. Since, this trend allows countries to keep in touch easily, I believe that several benefits like innovation and knowledge sharing can be posed.
If people have easy access to visiting foreign countries, education and information exchange may significantly improve. This is evident with the increasing number of students from all across the world enrolling to foreign universities. If lots of talented individuals from diverse backgrounds unit under one specific environment, remarkable innovations can be achieved in both academic and social spheres. A strong example can be the National university of Singapore (NUS); By the end of the 20th century NUS was relatively unknown globally, and was not ranked among the top universities of the world. However, after opening its doors to foreign students, its performance significantly improved. It”s rise can be associated with the number of likeminded people from diverse backgrounds who share a single vision of academic excellence but in different ways. Now, in 2025, NUS holds one of the greatest rates in QS top universities (17th place in top universities of the world). NUS is just one example of success driven by an interconnected world, while there are even more significant cases.
Except for knowledge transfer, international mobility can bring economy improvements to many countries. This can be linked to tourism, which may significantly boost the economy by helping to local businesses grow. With the number of people visiting specific areas, the demand for particular products can rise, making some businesses more profitable. A great example is Thailand — an Asian country which welcomed over 39 millions of people in 2019 only. In fact, tourism, is one of the main sources of income in Thailand. Millions of jobs there depended on the tourism sector — hotels, transport, restaurants, tour guides and local markets. Without global connectivity, not only Thailand but many other countries might lose a major source of revenue.
In conclusion, global connectivity has improved dramatically since the 20th century. Although, there are some minor drawbacks like economic dependence, I am convinced that a globally connected world offers numerous advantages — particularly in academic, social and economic spheres. The cases of The National University of Singapore and that of Thailand prove the importance of this trend.
