In fall 2021, we had a task to get the secondary and high school students familiar with the AI Journey Junior conference, dedicated to artificial intelligence. The audience of AIJ Junior is kids and teenagers aged 10-17. They are representatives of generation Z, who do not watch TV and receive all information from the Internet, particularly, from social media. They find direct advertising annoying as it seems meaningless to them. We faced the challenge: How to tell students about artificial intelligence in an understandable and simple way? Computer games were the solution. They are a natural habitat of kids and teenagers. Today computer games have become a new media for self-expression, art, and science. We gave our audience a unique experience in the most popular game. We built a huge technological city of the future on a separate Minecraft server and held the AI Journey Junior conference there. In order to interest and impress gaming community, we developed a blueprint for the future metropolis in Minecraft with unique architecture and infrastructure. The height of the buildings reached 1200 by 1200 cubes, while the size of a character was 2 cubes. On the virtual stage of the conference building, we broadcast lectures and workshops dedicated to artificial intelligence. 18 well-known streamers on Twitch told to their audience about the conference and invited them to register on the AI Journey Junior website to join the conference.
