At Tesla's "We, Robot" showcase last week, the company remotely operated its prototype Optimus humanoid robot, with employees elsewhere controlling many of the interactions between the humanoid machine and the attendees, according to people familiar with the situation, cited by foreign media. At least one video online purportedly from the Oct. 10 "We, Robot" event shows an Optimus "bartender" admitting that it received "human help". The Optimus prototype can be controlled by artificial intelligence without external control.
