>there's no good reason to have babies born with Cystic Fibrosis, we know what genes are causing it.
IVF is expensive and difficult and all easily identified genetic diseases are rare, so until one of those conditions changes (cost reduction and better techniques, or so many diseases being discovered that the odds that you will be saving your kid from one become significant), it will not be used for this purpose but rather as something extra to do when IVF is required for other reasons.
We agree on that part, I am not advocating for editing every foetus' genome in the next 10 years. I just think it's short-sighted to put a ban on that kind of research based on fear of inequalities.
