 This year, Wikipedia is turning 20 years old. Happy birthday, Wikipedia. Wikipedia began with a very radical idea. Imagine a world in which every single person on the planet is given free access to the sum of human knowledge. The knowledge in Wikipedia comes from people like me. It takes a village to build Wikipedia. When thousands of people come together to share their knowledge voluntarily and build up a big encyclopedia, it's a knowledge revolution. The fact that anybody anywhere in the world can contribute to the platform makes the difference. Wikipedia is human because it is us. Today, Wikipedia has over 53 million articles across nearly 300 languages. In our era, Wikipedia has become the voice. For me, Wikipedia is the real way to change the world because the knowledge I share is the knowledge other people have. Everything is on Wikipedia. It is funny and it is brilliant. There's more heroes and battles. Pregnancy and childhood. The constellations of the zodiac. Women in science. The grandfather's paradox. A lot of time travel going back into the past. Even Dany and Dasu. And also sex in space. We're living amazing times, really. There's a saying that knowledge is power. When you know something, how does that make you respond? When the COVID-19 pandemic happened, as a medical doctor, I had to do something. Sharing crucial information about the disease. I've been editing Wikipedia since I was 12. I was born to do this. This is the human spirit. We live for knowledge. Because you can't really explain why so many people would take so much time and dedicate themselves to this project. But people do. Helping build free knowledge. This is our story. It's a human effort. Making Wikipedia the best site we can have. And a source of knowledge for humanity. To make humanity a better place.
