Is serendipity dead? I think things are moving in that direction. One of the unforseen consequences of digitalisation is that we are able to personalise incoming information. This is great on one level, but on another it allows for people to reinforce their own prejudices. More and more we are able to select sources of information (including news but also people) that match our own views. We are therefore less likely to have our views challenged and we are more likely to become hostile to opinions (or people) that do not match our own thinking. This is not good for quality debate or understanding.
