"Good at reading books, not seeking deep understanding; whenever there is a realization, one happily forgets to eat." (The "not seeking deep understanding" here by Tao Yuanming is quite different from the modern meaning, just right to start the discussion.) In our era of the internet, there is a peculiar phenomenon: the speed of word dissemination is always much faster than people's understanding of it. By the time it goes viral, the original meaning has long been dissolved, transformed, or even become unrecognizable. "Meme" has become cat and dog pictures with captions, PUA is equated with "emotional blackmail," and the "dark forest rule" is used to describe the crypto world’s survival of the fittest... The origins of these words actually have significant backgrounds. In this series, we will delve into their true meanings and evolutions. In the context of the Chinese internet, "meme" is almost equivalent to "meme picture." However, the origin of this term is not related to the internet. It comes from the concept proposed by Richard Dawkins in 1976 in "The Selfish Gene," used to describe how culture, ideas, and customs replicate and spread through imitation, similar to genes. I first read this book shortly after the Chinese translation was published, nearly twenty-five years ago. The essence of a meme is not "humorous," but rather "replicability," "transmissibility," and "evolvability." Even the word "meme" is actually a combination of the ancient Greek word mimeme (to imitate) and the English word gene. This naming itself implies its biological analogy background. This term was born in 1976, more than twenty years before the internet became widespread. What Dawkins referred to as a "meme" can be a line from a book, a melody from a song, an artistic conception in a painting, or a scene in a movie. "Looking back at the desolate place, returning, there is neither wind nor rain nor sunshine," Su Dongpo's poetry has endured for a thousand years, relying not on genetic inheritance, but on human imitation and transmission. Therefore, poetry can be a "meme," and philosophical thoughts and scientific theories can also be "memes." Good memes can be passed down, while mediocre memes will be eliminated by the times — this is the cultural aspect of "survival of the fittest." In the internet age, this speed of replication and evolution has been amplified to the extreme. Every meme picture we share today, every popular phrase we quote, is part of meme dissemination, only the medium has changed from word of mouth and printed materials to global instant connectivity. This is also why in the crypto world, "meme" has given rise to a brand new financial phenomenon: memecoin.
