I've never been on a transhumanist mailing list, but I would have said, "Being able to figure out what's right isn't the same as actually doing it. You can't just increase the one and assume it takes care of the other. Many people do things they know (or could figure out) are wrong."

It's the type of objection you'd have seen in the op-ed pages if you announced your project on CNN. I guess that makes me another stupid man saying the sun is shining. At first, I was surprised that it wasn't on the list of objections you encountered. But I guess it makes sense that transhumanists wouldn't hold up humans as a bad example.
