This article fails to mention why the currency circulated so fast. It was depreciating: it was defined as gradually losing value, so hoarding didn't work, and the people with money had a strong incentive to spend it. The article makes it sound like these currencies worked because they were local. They worked because they depreciated, and it's possible to do this on a national level.
A great book on this subject is In The Absence of the Sacred by Jerry Mander. He argues convincingly that the correct biological metaphor for technological progress is not evolution, but inbreeding. We are turning our attention more and more into worlds of our own construction.
Still, there's a lot of cool technology out there, and a lot of room to use it better.
I agree with the author: Heroes II is my favorite of the series, just for the innocent vibe. Also, Heroes IV is underrated. It got bad reviews because it came out buggy, but the bugs were fixed in updates, and of all the HOMM games, it has the best soundtrack.
I like this idea, but my problem is with the word "successful". Setting constraints rather than chasing goals leads to doing interesting things. But there's no guarantee you'll ever be recognized or rewarded.
I think a lot of harm has been caused by "automation" actually meaning "distributing parts of the same tasks among a bunch of people". As far as I can tell that's one of the main outcomes of "efficiencies" from computerization of offices, among other places: they mostly just made it feasible to carve up the job of e.g. secretary among everybody, adding to the number of things and processes each worker has to understand and deal with.
