3. Didn't a UNESCO expert panel just call for a temporary ban on gene editing on human DNA?

Yes, they did. UNESCO is suggesting a ban on ‘germline editing’ – that is, making changes to a person’s DNA that will be heritable – passed on to their descendants. We think that germline editing raises all kinds of big ethical questions that society needs to discuss and agree on.

We are definitely not advocating germline editing for humans. We aren’t in favour of ‘designer babies’. We are in favour of curing debilitating single-gene disorders on people that have already been born.
