CRISPR/Cas9 is an invaluable tool at the bench, but it is just a tool. It makes things easier than before, but if you look to the past, you'll see that scientists are cynical people. Attitudes will change slowly (though there are 3 biotech companies jockeying for the ability to use it in clinic). I think of siRNA and its revolution in biology -- it went from discovery to practical use everywhere in record time, just like CRISPR -- but the direction of research itself did not take that same radical shift. And medicine was improved too, but incrementally.
