Hyperloop One's Demise Marks the End of High-Speed Transportation Dream

Hyperloop One, the futuristic transportation startup backed by Elon Musk, is shutting down and laying off employees. The company, which aimed to revolutionize transportation with airless tubes, raised $450 million in investments and constructed a test track near Las Vegas. However, after a series of setbacks and a change in focus to cargo rather than passengers, the company is now closing its offices and selling its assets. This adds to Elon Musk's growing list of failed ideas, including recent recalls of Tesla vehicles and controversies surrounding his involvement with Twitter.
