I'm still not sold on it as a necessary system we'll have to adopt in the years to come, always seems based upon the inevitablness of large scale unemployment due to automatisation and no new roles created to replace them. The idea that a large portion of the population will have no choice but to be unemployed. More inclined to seeing it as an improvement to a large number of different benefit systems personally.

That aside I agree with what you're saying, main weakness of these localised trials is the lack of cultural changes surrounding it in the wider society. However I think these still have value in helping to understand how a system could work and build something which could be applied to a nation wide trial. Imagine that would be conducted in a somewhat small country with fairly low migration and an economy which isn't focused around agriculture/industry.

Think only after a larger scale trial like that is seen as successful would any countries seriously look to implement it.
