Paul Root Wolpe: It's time to question bio-engineering [TED]

At TEDxPeachtree, bioethicist Paul Root Wolpe describes an astonishing series of recent bio-engineering experiments, from hybrid pets to mice that grow human ears. He asks: isn't it time to set some ground rules?

I hate talks like this. Wolpe spends the first 17 minutes treading on painfully familiar (and tired) territory and the last two minutes asking the wrong questions. And worst of all, he offers absolutely no answers or directions in terms of next steps. Weak.
