Scientists can now harness the unparalleled power of gene editing to change the genome of any organism on earth, including ourselves. This has the potential to tackle devastating genetic diseases with no other treatment options, removing them from affected families for all future generations.
So why is society so uncomfortable with this? Why does the thought of changing maybe just one letter of the 3 billion in our genetic alphabet, in the genes of a tiny fraction of the human population, worry us so much? Maybe it’s time to challenge our oddly possessive feelings about our DNA and accept that with gene editing the ethical game has changed forever.
