I did see similarities between Yang and Elon Musk.
Yang's UBI is like Musk's reusable rockets, which seem naïve and from the future. Then the question is, if you yourself want to be that future. Both Musk and Yang say "yes". Therefore I am not suprised to see Musk endorsing Yang at all.
Naturally I don't think Yang will make it to the white house, but he is already making his contribution by putting up his thoughts on the table and "make America think harder". This thought will be consequential. He is already honoring the Chinese and Asian community in this nation.
We should all thank this brave fellow.
