The Road to Useful Autonomy
Sep 15, 2026
For years, Tesla has seemed on the verge of bringing full self-driving capabilities to its cars. The promise is that one day, without new equipment, every Tesla will gain the ability to drive itself. To Tesla’s credit, it’s come close. But its Full Self-Driving (Supervised) system still requires a human in the driver’s seat with their eyes on the road, ready to intervene at a moment’s notice. As a result, despite the undoubtedly impressive technology, the real-world utility of Tesla’s self-driving system remains limited. Now consider robot vacuums. They’re quite useful even though they frequently get stuck in corners or miss spots. That's because the reliability required for useful autonomous systems depends on the stakes of the tasks being automated. For low-stakes tasks, a system can be useful well before it’s highly reliable. But for high-stakes tasks, even a relatively reliable system may offer little practical benefit until it crosses the threshold at which users can delegate a task and trust the result. At that point, even a slight increase in reliability can yield massive gains in utility.
