Yes, I think that is a very good step for Finland, for any country; I hope they do give it a go! Such a plan holds promise for exploring deeper into our human potential, and we have the mechanization to replace human labor and pull such a system off, now.
As I was studying the history behind our economic systems, I learned that in the nineteenth century an unusual number of British pastors were among the scientists who contributed so much -- which happened because the pastors had a guaranteed living with leisure time to explore their curiosity. The funds were guaranteed because every landowner in the parish had to contribute to the pastor's income (or something on that order).
I would like to see Finland, or any country that tries this, develop more libraries, apprenticeships, and other opportunities for self-education and volunteerism.
I might look up how life is going in Finland; it seems I recall Finland or another of the Scandinavian countries has a high suicide rate? Also, one or two of them is among the countries with the happiest people, I think...I hope they do it, will be interesting to see how it works out.
