+It would be tempting at this point for me to describe every single
+problem and fix. But that would be boring and if you're really
+interested in that, it's all described in the paper that accompanies
+this talk. Instead, I wanted to try to classify the delays according
+to their root cause. So we should be able to see, I hope, that some
+problems are easily fixed, whereas others are "institutionally" or
+"organizationally" very difficult to deal with.
