This is the kind of miserable critic who asks "yes but what's the practical use of it ?" when confronted with an exciting new scientific discovery. A fun-squashing, party-pooping, 1-dimensional, monochromatic-minded coin. Humans are born for adventure. It's who we are. We explore and we discover and we don't need to have practical reasons. Often it's only in retrospect that the utility of an adventure becomes evident, you simply can't know everything in advance and it would be no fun if you could. This is exactly the sort of (informed and calculated) leap of faith our species needs right now, poised as it is on the verge of possible armageddon.
