This is an excellent article on the unlikelihood of 'Designer Babies' any time soon,
Better babies?, by Steven Pinker, an Evolutionary Psychology Professor at Harvard, previously with MIT. Oooh. Ahhh.

But despite all that, he's got a very fun book to read. Its called The Blank Slate book, and its eye-opening, funny, and challenging. I haven't gotten a firm handle on all of the implications, but he bashes both Right and Left in this book, and I think the implications are huge. Its time that we start factoring Human Nature into our discussions, and toss away alot of the wishful thinking of the 60's Utopian idealism. When I've done more background reading I'll write something more about the Blank Slate, a Pulitzer Prize contender.
