Science is overrated. Sure it gave us the periodic table, antibiotics, and bouncy balls, but it also gave us atomic bombs, anthrax, and super difficult homework. That's the message of Cat's Cradle, or, at least, that's what it might seem like at first glance. But if you dig a little deeper, you'll discover that it isn't science that's really on trial here. It's the thought that science can somehow be considered separate or above the atrocities it helps create, such as the atomic bomb. Characters like Asa Breed and Felix Hoenikker consider their research distinct from the way the world decides to use it. But in Cat's Cradle, this mentality is considered wrong, and science is held responsible for the chain of consequences brought about by its research: both the good (bouncy balls!) and the bad (homework).
Cat's Cradle sees science and technology as tools that can be used for evil as well as good.
Every bit of advanced technology featured in Cat's Cradle takes a life—including cars and airplanes.
