"Ben Franklin, yanked into our own era, would be surprised and delighted by some aspects of his Future. Other aspects would horrify, disgust, and frighten him; and this is not because our world has gone wrong, but because it has improved relative to his time."

How do we know that it's improved? Isn't it equally plausible that Franklin would be horrified because some things in our world are horrifying, and his own moral thinking was more rational than our own? Does moral thought gets more rational all on its own? It seems as though it might be difficult for moderns to know if moral thought were less rational than it used to be.
