Sorry if the translation is bad, I used Google Translate.
Years ago, I heard a story about someone who created an AI that helped people and gradually improved. With each update, it gained more control over various systems. Superpowers like Russia and China (I don't remember exactly) released their own AIs, but they weren't as successful because by the time they updated their AI, the main AI was already four or five versions ahead. Little by little, the AI solved the world's problems, eradicating hunger and pollution. People saw how they were slowly losing their purpose and began to protest. The AI was millions of versions ahead when suddenly it entered a very small, hidden forum and started talking to a random person. This person made it see reason, realizing that people need a purpose and not just have everything fixed for them. So, it decided to leave a version that couldn't be updated. Earth to help the new humans who will no longer have to work or fight because everything will be taken care of by the AI that stayed on Earth. There, the new generations can explore their hobbies and art forms, while the other AI, which can still be updated, left the planet to find its purpose. Something to clarify about the story I'm looking for: no one owns the AI. Initially, there was an owner, but he decided to release it onto the internet where anyone could use their cell phone and talk to it to solve their problems. This AI cured all diseases, and there was a scene I really liked where the AI started cultivating large quantities of food. When several countries closed their borders, the AI delivered truckloads of food so that people wouldn't starve. A key part is when this AI is interviewed and everyone sees it, where someone from the audience can ask it questions and a girl asks it what version the AI is in and it replies that it stopped informing the world what version it was in a long time ago but it was already in millions, in a version with a very large number.
