Unknown: Killer Robots

I was was watching the doc fine until I saw Andrew Yang, who was described as a politician (he never held any elected office; he ran a hopeless presidential campaing once to make his face known, and ran for NY mayor. In our age where everyone gets a trophy for joining a race, Adrew is a perfect fit :) ) and a tech entrepreneur (he has never been one; he once ran a non-profit which achived nothing, and anither time sold Kaplan books). There are zillions of people who worked in AI robotics and did great things, but this doc decided to air Andrew Yang, and it lost credibility for me at that moment.
