Computational Complexity is not a Spectator Sportmeaning that to truly understand and appreciate computational complexity research you need to be an active researchers yourself.
But we can't keep the attitude that computational complexity can only be appreciated by complexity theorists or we become closed and irrelevant. We need to sell complexity and the rest of theory to the scientific community and the public at large.
We can learn some lessons from great spectator sports like baseball. One cannot truly and deeply understand baseball unless you have played the game on a regular basis. But professional baseball knows they wouldn't exist without their fan base. They make the game interesting to fans at different levels of understanding, from casual fans who barely know the basic rules of the game, to sophisticated fans who understand the nuances of strategy.
While I will never expect to see us proving theorems in front of fifty thousand screaming fans, we should aim to make our work understandable and interesting to fans of theory who have different levels of knowledge of the field.
