Thanks, very interesting.
One nit to pick - their math (or chart) can't be right:
the teen birth rate has fallen so fast — 38.4 percent annually between 2007 and 2013
I think they need to take out the 'annually'.
And I'm just curious as to why homicide is so much higher in US (though going down, which is good)? I'm guessing 'access to guns' isn't the full answer.
And I'm not too worried if Moore's Law is slowing. Even if progress of that measure slows (number of transistors per chip), there is so much that can be done with the current technology, and improvements made in how it is used and packaged. Software can be improved in efficiency a lot, I think present programming methods have lots of trade-offs.
The chart on Solar power getting cheaper isn't really such great news though. The cost decline of the actual solar cell itself has really flattened, and is now a relatively small part of the overall installed cost. The cost of the other pieces (metal racks, wiring, inverters, labor), are flattening as well, and aren't really candidates for big improvements, and labor will likely go up.
But lots of positives there.
