I couldn't imagine wanting to clone my dog after he dies. I wouldn't want a simulacrum of him and it would be disrespectful to his memory to think I could replace him with a physical copy - not to mention unfair on the cloned dog itself.
I think he is absolutely right in the world. But I think many people are so attached to their dogs that they would not think twice about doing it, even if they do not realize that it will never be the same. Nothing in this life can be the same, it will always be worse or worse. best
