Tesla's Optimus Gen 2 humanoid robot was "talking" at Tesla's October 10 event, but it is unclear if it is human assisted or not.

One of the highlights of Tesla’s “We, Robot” event wasn’t the self-driving cars but the allegedly autonomous robots. Tesla’s Optimus bot isn’t new, but this is the first event where actual robots joined the stage—and the crowd—rather than a person in a robot costume. Or was it?

Tesla just unveiled its long-awaited Robotaxi aka Cybercab, an automated electric car that CEO Elon Musk claims can drive itself without human intervention. If it works, you may end up having fewer awkward conversations with cab drivers about presidential elections. However, this wasn't the only tech Musk revealed during Tesla's We, Robot event.
