The author uses Saudi Arabia as an example as a country with UBI that works badly. First of all, I have no intimate with if there is any implementation. The author does not provide any sources, so that's not much help. A cursory Google search leads me to doubt this claim [1]. The author claims >50% unemployment in the country, again doubtful [2].
Then, the article states that proponents of a UBI claim that it allows people to self-improve and take risks, equating this with a transition from a low skilled worker to a high skilled one, which seems a far stretch. Of course automation removes low skilled jobs; but more training does not automagically turn everyone into PhDs with un-automateable jobs.
Then there are even more wild claims about it leading to a demise of the American democracy, where I don't even begin to see how the author came up with it.
