I've been saying for a long-time, real robots don't need to be humanoid. In fact it's better off formless.
But it's fear-mongering like these that are holding us back:
The researchers in the audience found themselves presented with two propositions. The first was that they were the stewards of an exceptional breakthrough. “We’re in the midst of one of the greatest onetime events in history,” declared the MIT economist Erik Brynjolfsson. Attendees were asked to predict when machines would become better than humans at all human tasks; virtually all were willing to put a date on the event, and their median answer was 2050. The second proposition was more complicated, because it asked the researchers to consider that this breakthrough might be a very bad thing. Famed technologists have been warning about the threats that AI might pose: not just Musk and Tallinn but Steve Wozniak, Bill Gates, and Stephen Hawking, who recently said that “the development of full artificial intelligence could spell the end of the human race.” Or as Musk has said, “With artificial intelligence, we are summoning the demon.”
