...human cloning, would probably be accomplished within the next fifty years...he did have some fun wondering who should be cloned: Ringo Starr? Frank Sinatra? Raquel Welch? the shah of Iran? The list itself seemed to vindicate C. S.

What does it mean by "enshrine a certain set of ideals in a "preordained" gene pool"?
If you 'enshrine' something, you give it a special status, so that it can't be questioned or challenged. By pre-ordained gene pool, i suppose the writer means that we would create a gene pool that reflects our biases and desires. It is unlikely that Ringo Starr would have resulted from planned breeding, and this shows the weaknesses. We'd want tall, handome/beautiful people corresponding to our idealised view of the best of humanity.
