I'm excited about CRISPR and what it means for the future of humanity. I say we focus on illness and disease first before we start making designer babies (see the movie Gattaca). Here's a link to my favourite science news website and a few CRISPR articles: https://www.sciencedaily.com/news/plants_animals/crispr_gene_editing/
Make no mistake about it though we will have designer babies. Is this the end of humanity as we know it? I hope so. Why settle for all the faults we now have? Yes we should take things slow and be cautious as there are always unintended consequences.
