Actually he misses a second point too ... the reason you don't see exponential growth in human-led research is that we each start out with "empty" brains. To become truly knowledgeable in a field may require a life-time. I'm not arguing that the singularity is near either, but machines would have the advantage of creating offspring that are already as knowledgeable/intelligent as themselves. Something I couldn't do for my children.
