The world has moved on to the stage for embryo gene editing. There will be someone, somewhere, who is doing this. If it’s not me, it’s someone else. I know this is probably going to be the world’s first. So if it’s not safe, or have any problem, it may ruin the entire field, and people may lose trust in the new technology. I feel a strong responsibility that it’s not just to make it first but also make it an example, how to perform things like this, consider morality of the society and consider its impact to the public.
