Robots beat Usain Bolt's 100m record, so why can't they replace human workers yet?

Timothy B. Lee highlights a deep dive by Kai Williams on Understanding AI tackling anxiety about mass unemployment from humanoid robots.
The article walks through recent headline demos: Tesla's Optimus serving drinks in 2024, Unitree's backflipping synchronized dance at the 2026 Spring Festival Gala, and a robot running 100m in 8.86 seconds at the 2026 World Humanoid Robot Games — beating Usain Bolt's 9.59s human record, when last year's fastest robot needed over 20 seconds.
But after talking with many robotics experts, the author argues there's a huge gap between demos and real work capability, and matching human workers could still take years, possibly decades.
