Very interesting, Marigold. I hope this will be the future for producing cheap and effective treatments for a whole range of conditions.
A couple of weeks ago on The Big Questions was a discussion about the potential for preventing heritable conditions by altering the human genome. Again a whole range of views as you might expect with fears by some that it was the thin edge of the wedge to a Nazi style of genetic selection.
All these things need rigorous testing and policing. But ultimately I see it as a bright new future for our species and, indeed, for the whole planet.
