“Cultures change and the ceaseless churn builds empires just as easily as it razes kingdoms. There is always some part of a culture that is dead, dying or lying dormant in wait for the right person to come along with the right set of ideas and the right type of audience. Complaints about the exhaustion of the field have always been with us and will hopefully always be with us as they are a sign that the world of written SF is still complex and vibrant enough to contain multiple factions with different ideas about what SF ought to be doing. The only time people should really start to worry about the exhaustion of SF is when people stop complaining about it as that means that people have stopped disagreeing and when people stop disagreeing it’s generally a sign that people have also stopped caring.”
(Jonathan McCalmont, ‘Cycles of Exhaustion’)
