In this series I work with the topic of expertise in the modern environment. The network has created millions of online experts on any issues. Everyone who has a desire and confidence can out-speak his instant opinion. This process shifted the weight of expertise from large institutions and dozens of persons to millions of individual leaders of opinion. Each event usually has two sides of one coin. We received more independent opinions and reduced the influence of dictatorship. But such a large number of independent thoughts makes it rather difficult to choose one thought that can be trusted. There is a high risk of becoming numb in the inability to choose the one truth.
