How might universities that drew students from many places affect european life in the future

Universities in Europe have been successful in attracting students from all over the world. This is due to several reasons, such as the quality of education and professors, the multiculturalism that is found in many regions, the promise of free movement, etc. This success might significantly affect European life in the future. It is very likely that cities will continue to become more multicultural. Moreover, it is very possible that as more cultures are found in Europe, European cultures themselves will be transformed as well.
