CRISPR is amazing, at least in my perspective, you see I'm prone to diabetes and heart disease from both my mother and father side, and if I had the chance of eliminating those traits from my future children DNA so they will have a longer and better life: of course i will do it.
My fear with genetic modification is that human race is not fair, that technology will only be available to those who can pay it or those living in developed countries with access to it, which means widening the space between social classes.
Lets not hope this prediction becomes true.
