 You'll get to watch a home run sitting in your favorite chair. See the news as it's happening. Because if I can broadcast a single point of light from here to there, then anyone can broadcast a bunch of points of light that make up an image and send it as far as they care to. Soon, we'll get pictures from all over the world and learn about our comrades in other countries. Hell, other planets. If we could see their faces, we'd understand them better. And all our differences could be settled around tables instead of going to war.
