In 2013, Elon Musk published a white paper that teased the idea of zipping from Los Angeles to San Francisco in just 35 minutes through a vacuum-sealed tube — a system he called hyperloop. The idea “originated out of his hatred for California’s proposed high-speed rail system,” according to his biographer Ashlee Vance.

Ten years later, the most high-profile startup that tried to follow in Musk’s footsteps — Hyperloop One — is closing its doors. And the news of its demise broke less than two weeks after the Biden administration announced $6 billion in funding for high-speed rail projects across California.
