We've put huge resources into predicting tsunamis, hurricanes, and earthquakes. HIV/AIDS is like an earthquake that's lasted 30 years and touched every country on the planet. We have such incredible capacity to think about the future, it's time we used it to predict biological threats. Otherwise we'll be blindsided again and again.
Trying to understand the way nature works involves a most terrible test of human reasoning ability. It involves subtle trickery, beautiful tightropes of logic on which one has to walk in order not to make a mistake in predicting what will happen. The quantum mechanical and the relativity ideas are examples of this.
