What is a negative effect of being able to experience the same things worldwide through modern technology?

The shared experiences can dilute traditional cultures.
Modern technology, most notably the internet, has made possible instant communication and the democratization of the availability of information and knowledge. However, as a negative correlate of this fact, modern technology tends to focus on global trends and the cultures where these are originated, making experiences uniform, which can dilute, or at the very least, undermine, the contributions that traditional and non-dominant cultures may contribute to the globalized dialogue that modern technology implies.
