OpenAI's robotic hand doesn't need humans to teach it human behaviors

Gripping something with your hand is one of the first things you learn to do as an infant, but it's far from a simple task, and only gets more complex and variable as you grow up. This complexity makes it difficult for machines to teach themselves to do, but researchers at Elon Musk and Sam Altman-backed OpenAI have created a system that not only holds and manipulates objects much like a human does, but developed these behaviors all on its own. Many robots and robotic hands are already proficient at certain grips or movements -- a robot in a factory can wield a bolt gun even more dexterously than a person. But the software that lets that robot do that task so well is likely to be hand-written and extremely specific to the application. You couldn't for example, give it a pencil and ask it to write.
