Elon Musk Tests Tesla's Life-Size Robot Optimus Amid Controversy

Elon Musk took Tesla's humanoid robot, Optimus, for a test walk, showcasing its new human-like appearance and movement. Despite Musk's vision of robots performing unsafe, repetitive, or boring tasks, some critics expressed concerns and humorously suggested "kill it with fire." The latest version, Optimus Gen 2, stands at 5 feet 11 inches tall, weighs 121 lbs, and can run at a speed of 5 mph. Musk aims to refine the robot and eventually produce millions of units, although this venture diverges from Tesla's primary focus on sustainable energy. Additionally, Musk agreed with a prediction that there could be about 1 billion humanoid robots on Earth by the 2040s.
