Life's happened to me this week, so I don't have time to do detailed, thoughtful posts with links and everything. Instead, today I'm sharing two videos that build on my post from Monday, both from Ted.com. The first is on big picture news—what textbooks 100 years from now will pinpoint as pivotal moments. The second extrapolates from current society and population growth, and paints a picture of life 200 years from now. Enjoy!
