Semi-autonomous living

Tesla's humanoid robot, Optimus, promises to perform low-value repetitive tasks so humans can do higher-value work. Musk is correct that robotics will be worth more and be of greater importance than autonomous driving. A self-driving car is essentially a robot run by batteries. This is his proof of concept. The end goal is a robot powered by the same lithium battery found in Teslas. A robot more versatile than Agility Robotics' "Digit" or Boston Dynamics' "Atlas". Ford currently uses Digit for deliveries. I recall someone saying that Tesla's business is not cars, it's batteries. Battery and a charging station to power anything.

Now, Mazda will resume work on a rotary motor that produces electricity to power the entire vehicle and systems inside. It is a plug-in hybrid not fully electric. Just imagine if electricity can be created without cords? That would be solar or wind power.
