The British actor and writer Stephen Fry pretty much closed all the arguments about the benefits of gene editing for me when he, a man with bipolar disorder, spoke of how wrong it would be to use gene editing to eradicate bipolar disorder and other conditions affecting mental wellbeing.
Being bipolar is part of who I am, Fry said, (I'm not quoting directly but from memory,) implying that if his bipolar disorder had been removed pre - birth he would be a very different person to the one who entertained us so ably.
He then wen to to list great figures in the arts and sciences who had been affected by some kind of genetic disorder and pointed out how much poorer the world would have been without them.
The nightmare prospect of a world filled with identically anodyne, perfect being ought to be enough to convince anybody that scientific work aimed at creating gene edited "designer" babies must be strictly controlled and actively discouraged unless it is intended to prevent a very specific ailment.
It is time we realiged our humanity with nature. That does not mean going basck to medieval medical practices, but it does mean accepting that out flaws and imperfections, like our mortality are integral to our humanity.
