I read the hardcover version when it came out and have been disturbed by it ever since. I am not a religious zealot and believe, or rather hope, that I'm not narrow minded. (I believe in evolution, I have a Ph.D. in engineering, etc.) But while reading the book, I sometimes gazed at the photo of the author on the dust jacket and saw a man in the prime of life, talented in every way, successful in every way, honored academically and professionally ... and he describes in his book how he wants, expects, to play God. I recommend the book highly because it made me think and it has stayed with me ever since. Still, I am frankly frightened by his vision. He and his research can do so much good, let's hope that he knows the difference between good and evil. Strong and melodramatic words on my part, by they're heartfelt. In any event, read the book.
