And yet I can understand the skepticism and fear. We have not had yet a big scale "experiment" (i.e. a whole country implementing it). It will have bigger yet to resolve implications (e.g. what's the effect on migration etc.).

(And I'm a big proponent of UBI)

But I think it's just a matter of time that this will become reality, we're to rich (in the western world) to fiddle around with "annoyances" like poor people, and I strongly believe that it will increase creativity, innovation and thus also GDP which may be probably the biggest argument for policy makers.
