I'm not remotely sold on UBI (not sold against it either) but this article is just nonsense. It's very obviously intended to "preach to the choir" and not to discuss UBI in any serious terms or to convert anyone to the concept of UBI. In fact, for me someone who is skeptical of UBI but not against it, it pushes me further away from the idea of UBI.
"If the supporters of UBI think like this, I don't want to be anything like them"
