I agree with the neighbor comment, 2015 was a long time ago. See the state of the art today: Agility Robotics Digit: https://www.youtube.com/watch?v=Jycdks836

I agree with the neighbor comment, 2015 was a long time ago. See the state of the art today: Agility Robotics Digit: https://www.youtube.com/watch?v=Jycdks836bY https://www.youtube.com/watch?v=Jycdks836bY Boston Dynamics Atlas: https://www.youtube.com/watch?v=tF4DML7FIWk https://www.youtube.com/watch?v=tF4DML7FIWk Neither of those robots use a static walk. That is obvious enough in the above Boston Dynamics video, but Agility Robotics also just released a little video explaining their (very robust) dynamic walking system: https://www.youtube.com/watch?v=mpxrnrR_Tsg https://www.youtube.com/watch?v=mpxrnrR_Tsg It seems clear the basic hardware to do humanoid walking is technologically achievable today. Personally I would think Tesla would be better suited by copying or buying Agility Robotics as Digit is a smaller robot and it looks cheaper than Atlas too. Better for working in a warehouse alongside people as shown in the top video link in this post, and they seem a smaller company than BD and so cheaper to buy. Musk is very happy to buy firms that produce tech his companies need. As far as the software problem, it is a big one to be sure. I don't think they have all the pieces to the puzzle, but I do think Tesla's Dojo AI system has promise for training a machine like a humanoid. Their system is designed to ingest experience and produce neural nets which can navigate in the real world. They may be willing to take a bet, despite the clear risks, on using this system for humanoids. If they buy Agility Robotics, rev the design to add their AI system (which is extremely powerful AI hardware with their own custom processor), they could be in production on prototypes within a year. This all has the disclaimer that success is still very hard and not guaranteed, but then that's the kind of thing Musk loves to throw resources at. Also: I do not work for any companies in this field. I am making a farming robot (see profile).
