       | 
       | They add a visual component, which with 30 minutes of real world
       | data, through a technique called Cross-Modal Supervision (CMS),
       | is able to improve walking performance significantly!
       | 
       | They can even distort its vision (turn the camera) and it learns
       | to adapt!

         | When one robot learns, millions of them learn
         | 
         | When millions of cars learn, they all can send data back to the
         | mothership which crunches the numbers and they all improve
         | 
         | Even without AI, this is how technology has always advanced.
         | Humans simply improved things and copied it to all the
         | implementations.
         | 
         | So basically, when it comes to competing with robots or
         | software, it is a losing proposition in the long run. No
         | biological animal can evolve faster than this.

       | It's not the learning that's the magic. It can be 30 minutes or
       | 30 days. It hardly matters. Where the sparks fly is that learning
       | can he transfered in .3 seconds to 300,000 other robots. And then
       | updated as needed.
       | 
       | Now compare the to humans.

         | The fact that it is learning online in fractions of a second to
         | prevent falling (I would say) is pretty magic!
