Leadership from below is a perspective on leadership: No need for a position in a hierarchy to have influence. It is also a perspective on life: lead when you need. It is not just a trend. In fact it is a stable feature of any society, but it has recently become trendy. However, despite disruptive tech...hierarchy remains systemic part of society. Complexity means that delegation is necessary. Also, people love to delegate. So, the pendulum swings back. However, hierarchy will need re-legitimation.
