From what I've read about it (I'm from Hawaii so this has a special place in my heart), it will be on a very limited scale to start with. I would be weary to put all my eggs in the basket of "they're implementing a UBI" since it's entirely likely that the project fails due to the implementation process. I still think it's great to see somewhere try it in the US, but I am going to reserve judgment on whether it turns out to be successful until more information and data is available.
