"I don’t know how people will look at this ethically.”

Some scientists out there are doing such fascinating, wonderful work. Others busy themselves with fascinating, seriously disturbing work. It's like the old Seinfeld joke about the scientists who came up with seedless watermelon - what is the thought process of these people as they choose their careers? "Oh, screw cancer, screw alzheimer's - I wonder if I can turn an embryo into sperm? That would be wicked!" Don't miss Pogo's comment on the banality of evil. So, dear scientists, as the professor suggests, "You might want to think about it. You know, yourself."
