What, then, made this rogue researcher think that his ‘achievement’ would be welcomed? One possible factor is that He claimed that he was influenced by the words and actions of key US and UK scientists. He attended and was an invited speaker at several meetings about gene editing, including several focused on the ethical acceptability of human germline modification1.
