Al Jazeer’s “Counting The Cost” economics program this week <http://www.aljazeera.com/programmes/countingthecost/2017/08/cryptocurrencies-digital-gold-rush-170826082909447.html> talks, among other things, a bit about: * Cryptocurrencies (e.g. Bitcoin) -- is it too early to start regulating them? Start worrying about their use for illegal activities? Start investing in them? * Autonomous military weaponry -- should we start banning the creation of weapons that can take their own decision to shoot to kill? Or is more research needed? By the way, mentioned in passing in the latter segment is that Samsung-made autonomous guns are already deployed along South Korea’s border with its northern neighbour.
