Elon Musk on Optimus：
"You've probably seen lots of impressive demonstrations of robots on the Internet， but those demonstrations you're seeing are pre-programmed or remote-controlled. So there is no humanoid robot that is actually able to do generalized tasks. Optimus will be the first one that is capable of doing that.
It's not just a demo， it's genuinely useful in day-to-day life. Optimus is designed to have full human dexterity， so a hand that has the same level of dexterity， if not higher， than a human hand.
The human hand is an incredible thing. The more you study the human hand， the more amazing you realize how amazing hands are. The nuances of how human hands work are amazing. Optimus will have that capability. It will have superhuman dexterity， so it's really going to be quite something."
