I'm reminded of the Ender series of books by Orson Scott Card or the movie Gattaca. Those were stories and speculations but this is real. With CRISPR we now have gene splicing that can be exact, quick, and easy. While it may open up a whole new front on cures for scores of diseases, it could also become an ethical horror story. Where do you hope such power can lead? What do you fear about it? Could CRISPR be responsible for many future headlines?
