Prime Minister Netanyahu laid out Israel’s “red line” on Iranian nuclear development in his speech to the UN General Assembly: 240 kg. of 20% enriched uranium. There are two points that are relevant to this threshold. First, according to the International Atomic Energy Agency, Iran already has 189 kg of 20% enriched uranium. Second, one cannot build a bomb from 20% enriched uranium–you have to enrich above 90% to attain a critical mass for a bomb. So the “red line” will be reached next spring, even though it will not signal the capability to build an atomic bomb.
One of the most extraordinary innovations of the technological revolution is the development of digital fabrication, or 3-D printing. Essentially, digital fabrication is quite literally printing out objects that used to be assembled by hand. Just a moment’s reflection is enough to appreciate what such a change will do to the world of work (and then think about how you would fit into such a world). It is a long essay with a lot of detail, so I won’t ask any quiz questions about it. But I recommend it highly.
And now, a moment of world politics humor.
