Elon Musk has highlighted population collapse as a major global threat over the next two decades, challenging the outdated notion that overpopulation is the primary concern. Musk emphasized that population decline, rather than explosion, will pose significant challenges for humanity. Concurrently, Musk and Tesla are advancing artificial intelligence and robotics, marking 2025 as a pivotal year with the launch of unsupervised full self-driving (FSD) technology, which Musk described as potentially the most important milestone in Tesla's history, even surpassing the launch of their first car. Tesla is also developing humanoid robots, which Musk predicts could number in the tens of billions, with widespread personal use anticipated. Meanwhile, China is emerging as a leader in humanoid robot deployment, having delivered the first batch of 220 Mornine robots to clients globally, including automobile 4S stores. These robots are equipped with advanced technologies such as 3D lidar, panoramic cameras, and large language models. The integration of humanoid robots into workplaces, particularly in China, is prompting discussions about their safety, design, and functionality. Experts foresee humanoid robots transitioning from laboratories to real-world applications, potentially transforming factory floors and other industries within the next 15 years.
