Wang Xingxing doesn’t have Musk’s charisma or packaging skills, so the speed of his decline will be much faster than the time it takes for robots to mature and reach mass production. Old Ma is different—he used SpaceX as a nesting doll to sell off most of the overvalued products. Next up is the brain-machine interface. I’m really curious to see how this will be sold at sky-high valuations in the next bull market.
