Google Creates a Digital Fruit Fly That Thinks, Moves, and Sees Like the Real Thing In a stunning leap forward for both artificial intelligence and biology, Google has developed a fully digital fruit fly—a virtual insect that lives inside a computer and behaves just like its real-world counterpart. This digital creation walks, flies, sees, and responds to its environment with lifelike precision. The journey began with a meticulous reconstruction of a fruit fly’s body using Mojo, a powerful physics simulator. The result was a highly detailed 3D model that could mimic the fly's physical movements. But a body alone doesn’t make a fly—it needed a brain. To create one, Google's team collected massive volumes of video footage of real fruit flies in motion. They used this data to train a specialized AI model that learned to replicate the complex behaviors of a fly—walking across surfaces, making sudden mid-air turns, and adjusting flight speed with astonishing realism. Once this AI br...
