We think information is available and that we can learn and find everything. However, people create almost impenetrable walls - so-called echo chambers. They let us feel comfortable inside our own information bubbles. It is like an irresistible force, like gravity, pulling some people together and separating them from others. In this analogy, just as a person once stepped out into open space, I hope that one day we will be able to step out of our bubbles and truly hear each other.
