GOOGL is just too comprehensive! Imagine this: you’re tasked with creating a detailed circuit diagram of every power plant, every high-voltage cable, every substation, and even every switch and wire in every home in a massive metropolis. Now, imagine that the actual space this diagram represents is only the size of a grain of coarse salt. That’s exactly what Google Research, in collaboration with top research institutions, has just accomplished: they’ve fully mapped the entire central nervous system of an adult male fruit fly. And it’s not just the brain—it includes the brain, the visual nervous system, and the thoracic-abdominal nerve cord, which is equivalent to the human spinal cord. The complete map encompasses over 166,000 neurons and a staggering 125 million synaptic connections. To create this map, scientists sliced the fruit fly into thousands of ultra-thin, nanometer-scale sections and scanned them with electron microscopes to generate massive amounts of image data. Google then deployed specialized neural network algorithms to stitch millions of 2D slices into a 3D structure of the neurons. Even with top-tier AI assistance, human researchers still spent a total of 44 person-years verifying and refining the map. When you truly understand this neural roadmap, you’ll realize just how intricate the mechanisms of biological evolution are. For instance, scientists discovered that when a fruit fly is flying, walking, or avoiding obstacles, its brain isn’t micromanaging every single leg movement in real time. Most of these actions are autonomously handled by local neural circuits near the limbs. Isn’t that basically natural edge computing? This also explains why Google consistently maintains such a high ceiling in the industry. Most people see Google as a company that does search, ads, and YouTube. But at its core, it’s actually an engineering and computational powerhouse designed to solve massive, complex problems. From AlphaFold predicting protein structures, to reconstructing slices of the human brain’s cortex, to now mapping the entire central nervous system of a fruit fly. When a company can deeply integrate cutting-edge computational power, AI algorithms, and fundamental scientific research, it’s not just working on today’s business—it’s laying the foundation for humanity’s technological future for decades to come!
